Katsuko is an ENTJ personality type.5) In every sense of the word, Katsuko is a driven visionary and a skilled leader. She is charismatic and has a natural ability to attract followers, command soldiers in the Star Army of Yamatai and construct successful and result in bearing strategies. She has proven herself as a leader through her role as Taisho of the Fifth Expeditionary Fleet, the Seventh Fleet and her final role in the re-establishment of the First Expeditionary Fleet at the end of the Kuvexian War. Her resilience is unmatched, even when her children Motoyoshi Tio and Motoyoshi Kiyoko betrayed and left her to create the United Outer Colonies she rebounded and rebuilt the Motoyoshi Clan.

She is confident, strong-willed, and energetic. She projects herself as a force to be reckoned with in a natural manner. She has a love for efficiency and goal setting that has helped with her successes over the years. She holds a naturally dominant demeanor and has a flaw when it comes to her arrogance, she has little reservation for being intolerant especially when it comes to those she perceives as traitors. She is bitter towards those who believe the lies and rumors about her clan. She is fiercely loyal to the Yamatai Star Empire, and a believer in the policies and actions of the Ketsurui Clan, specifically to Taisho Ketsurui Yui who has served as a mentor and cherished part of her life. In her early days, Taisho Kessaku Irim also served as one of her mentors, which resulted in a certain aggressive, strategic, and violent slant to her strategies.

Katsuko can be a very vengeful person but has a tendency to be very patient which results in the revenge being played out years after the incident which caused it and with decisive strategy.

In her personal relationships, at times Katsuko can come across as cold or emotionless, but this is more a result of her personality than her actual emotions. When it comes to romance, Katsuko is demanding of her lovers and rarely accepts anything short of what she considers perfection. Since the loss of her beloved, Shimizu-Motoyoshi Akina (清水本吉明菜) her focus romantically has been on Kage Yaichiro and Motoyoshi Eri, Katsuko despite her active love interests remains polyamorous and promiscuous in her pursuits of romance.


She enjoys diving and swimming, bubble baths, erotic dancing, belly dancing, and sexual exploration. She has a passion for designing starships; having designed the Hummingbird-class Colony Ship and the Takumi-Class Expeditionary Command Cruiser. She loves plum wine, sushi, o-sumashi, ankake udon, sashimi moriawase, karei kara-age, kakiage, tsukune; and pretty much any kind of fresh seafood. She loves the ocean and pretty much any body of water.


She bitterly dislikes extremely religious or self-righteous individuals. She has a tendency to take criticism to heart and has trouble dealing with failure. She dislikes amphibians, insects, and mice and is disgusted by foods prepared with beef or pork. She truly dislikes High Priest Velor Tomoe Tur’lista and Ketsurui Kotori. She is against Chiharuism and believes that it is Ketsurui Yui who deserves the faith of the Nekovalkyrja.

A Legacy of Commanding Fleets

History and Background

The History of Ketsurui-Motoyoshi Katsuko.


The Galaxy Expeditionary Group

Motoyoshi Katsuko's first command position was in YE 28 when she was promoted to Taisa and given command of the YSS Namiko, a Kyoto-class Carrier that was diverted from Zero Fleet at Nataria Fleet Depot. At the time she had been assigned to the Galaxy Expeditionary Group, which was a secret colonization mission under the orders of Taisho Kessaku Irim of the Star Army of Yamatai. It was a Transuniversal Teleportation Drive mission to another universe and is considered classified. 8)9) The mission ended when the colonization effort was determined to be unworthy of the Yamatai Star Empire's resources and the Galaxy Expeditionary Group was ordered to return to the Yamatai Star System by Taisho Ketsurui Yui.10) She was promoted to Shôshô and was given command of the Fifth Expeditionary Fleet as a result of her performance in the ex-universal mission.11)

The Fifth Expeditionary Fleet

The Fifth Expeditionary Fleet's first mission was to the Ahmar, to make first contact for the Yamatai Star Empire before the NSS Destiny/YSS Destiny, of the Nepleslian Star Empire could. Prior to the mission Taisho Ketsurui Yui also offered Katsuko to lead a program in which her new fleet would provide feedback and information to Star Army Research Administration on upgrade improvements for the Kyoto-class Carrier and Yuumi-class Battleship. The Fifth Expeditionary Fleet also received the honor to host a program to assist with the training of new personnel. 12) There was a riot on the YSS Destiny, and the crew of that ship was transferred to the YSS Confidence which was added to the Fifth Expeditionary Fleet under the command of Arild Bard.13)

The Fifth Expeditionary Fleet would be assigned to duties of colonization and exploration. Due to the scope of the mission, the YSS Akuro14) (NF-X5-01), a Chiharu-class Flagship was constructed at Ketsurui Fleet Yards and was assigned to be the flagship of the new fleet. The Taiie System was explored and colonized and became the headquarters of the fleet. Shimizu-Motoyoshi Akina (清水本吉明菜) was assigned as Katsuko's First Officer, upon her arrival on the YSS Akuro Katsuko gave her a private tour and a special gift; a blue teddy bear with a pink ribbon around its neck. 15) They developed a fast friendship and a great working relationship.

While the YSS Akuro was taking on its new crew, a problem developed early on when Ittô Heisho Elsar Iggagomi16), a negligent transfer who was infected by a Parasite-Type Mishhuvurthyar, attempted to sabotage the mission and killed four other soldiers. The soldier was apprehended and delivered an ominous message from the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) claiming they would all be dead soon. Katsuko executed the soldier and reported the incident to Star Army Command. 17)18)

Delta wing, the YSS Akuro's elite armor wing was established under Katsuko's orders. She placed Corro Adlich, a Nepleslian in command of the wing.19)

Katsuko and Shimizu-Motoyoshi Akina (清水本吉明菜) hosted a briefing dinner on board the YSS Akuro. The dinner hosted key personnel from the entire Fifth Expeditionary Fleet. At the dinner, Katsuko promoted Corro Adlich to Ittô Hei and announced that he would become the leader of Delta Wing. The plan was also to further discuss the colonization of Taiie IV but the dinner was interrupted by a power outage caused by a mutiny on the bridge by Shosa Yoshike, the fleet's Special Training Officer.20) The officer was unhappy she had been passed up for promotion in the Star Army of Yamatai, it was also later discovered this was the enaction of the threat that had been given by the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX). Katsuko, Shimizu-Motoyoshi Akina (清水本吉明菜), the members of delta wing and the crew of the YSS Confidence brought the rebel forces to justice.21) Under the direction of Emperor Kitsurugi Uesu, via the orders of Taisho Ketsurui Yui, the incident was classified to the highest levels of the Star Army of Yamatai.22) After the incident, Katsuko submitted recommendations for the “1D” refit for the Yuumi-class Battleship to Taisho Ketsurui Yui and Star Army Research Administration.

Katsuko climbed the ranks very quickly and was granted the rank of Taisho at the end of YE 28.23) She became romantically involved with Shimizu-Motoyoshi Akina (清水本吉明菜) and fell in love with her.24) Katsuko quickly developed an effective and unique command style, often easing the barriers between officers and enlisted soldiers inside of the Fifth Expeditionary Fleet during off-duty hours to increase morale. Several members of the YSS Akuro's command team and Delta Wing took shore-leave together on the YSS Hikari, an Ecstasy-Class Recreation Ship, following the thwarted rebellion.25)

At the end of YE 28, Delta Wing was renamed the 17th Kasairyuu Power Armor Wing. Katsuko oversaw the first contact with the Abwehran Star Empire having ordered the YSS Namiko on the Jaspis Expedition.26) The mission ended abruptly however when the YSS Namiko was recalled to deal with an emergency. Meanwhile the 17th Kasairyuu Power Armor Wing and the YSS Akuro continued operations in the Taiie System. By the first day of YE 29, the colonization of Taiie IV was completed under Katsuko's direction. 27)

A Year of Heavy Hearts YE 29

Katsuko was one of the first to convert to the new NH-29 body.

With the Taiie System being built up and the exploration and colonization of the rest of what would become the Bard Cluster underway, Katsuko requested the allocation of a Iori-Class Star Fortress, NH-XF-01 which would be named Taiie no Iori, was approved by Taisho Ketsurui Yui. The fortress had to be pulled from storage at Nataria Fleet Depot and was moved to the Taiie System.28) After the allocation of the fortress, Katsuko submitted recommendations for the “1D” refit for the Chiharu-class Flagship to Taisho Ketsurui Yui and Star Army Research Administration. Katsuko an Shimizu-Motoyoshi Akina (清水本吉明菜) produced two adult offspring, Motoyoshi Kiyoko and Motoyoshi Tio.

In early YE 29 Katsuko had Taii Suzuka Yukari transferred to the Fifth Expeditionary Fleet to be her Flag Aide. 29) A short time later, a tragic incident which involved Taiie no Iori occurred. A rouge element within Star Army Intelligence set out to kill Katsuko so they planted a malicious program which produced a sprite named 'Ichiro' onto the station. The station's KAMI infected many members of the Fifth Expeditionary Fleet Nekovalkyrja which turned on loyalists and set out to murder them. During the conflict, Katsuko's lover Shimizu-Motoyoshi Akina (清水本吉明菜) became infected and Katsuko was forced to kill her.30)31) The death of Shimizu-Motoyoshi Akina (清水本吉明菜) proved to be very traumatic for Katsuko, the event changed her forever.32) Taiie no Iori was rebuilt and renamed Akina no Iori in her honor. 33) As a result of the events that took place, Suzuka Yukari , transferred to the YSS Sakura.34)

Following the incident at Taiie no Iori, the Battle of Murf took the lives of Corro Adlich and the crew of the YSS Namiko. In Katsuko's grief, she arranged for her own assassination.35) Chujo Koyanagi Mayumi took command of the Fifth Expeditionary Fleet as a result of Katsuko's death. At the time it was believed that there was no backup and that Katsuko was lost forever. Taisho Ketsurui Yui and Princess Ketsurui Himiko both attended her funeral.36)

In YE 29, The Taiie System at the time was the capital of the Bard Cluster, and was the Headquarters of the Fifth Expeditionary Fleet. It was also the seat of power for the growing Motoyoshi Clan. Ut was attacked by the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX). The Shlarvasseroth-class Flagship, under the command of Melisson fired its transposition at the system's star which caused it to go Hypernova which resulted in the destruction of nearly everything in the Taiie System within a window of approximately fifteen minutes. Some civilian starships, shuttles, and other craft managed a narrow escape along with some of the Fifth Expeditionary Fleet, which included Hotaru Star Fortress and Himitsu Star Fortress. The loss of life in the tragedy was astronomical.37)

The Rise and Fall of Empress Motoyoshi Katsuko YE 30

Before her first death, Katsuko had contributed the plans of the Takumi-Class Expeditionary Command Cruiser, in her absence Taisho Koyanagi Mayumi took the finished schematics to Ketsurui Fleet Yards. One of the first ships produced was the YSS Yugumo, which would be given to her daughter Motoyoshi Kiyoko to command.38) The First Mishhuvurthyar War had turned sour for the Star Army of Yamatai and Katsuko was revived from a secret ST backup and returned to her place as Taisho of the Fifth Expeditionary Fleet and commander of the YSS Akuro II in early YE 30. 39)

Katsuko moved quickly to consolidate power in the Motoyoshi Clan she formed the Motoyoshi Bakufu under which the Motoyoshi clan and its tributaries formed a regional governance platform and initiated an effort to find a new home for the Fifth Expeditionary Fleet and survivors from the Taiie System and other colonies in the Bard Cluster that were now under Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) control.40)41)

Survivors from the Battle Of Taiie are taken to Pisces Station. The Zodiac-Class Star Fortress was still under construction and the station's PANTHEON system had not yet been installed. The station under the command of Taisa Marina Arisa is overwhelmed by displaced refugees of the First Mishhuvurthyar War, including those from Taiie. Through a series of unfortunate events and inexperience of the station's commander, refugees are subjected to improper living conditions, and some are murdered. The survivors from Taiie contacted the Fifth Expeditionary Fleet about the atrosities on the station. Taisho Ketsurui-Motoyoshi Katsuko responded and reported the incidents to Star Army Command. Taisho Kessaku Irim arrived at Pisces Station and arrested the station's commander.42)

Assisting The Lorath and Colonial Effort in the Yugumo Cluster

The Fifth Expeditionary Fleet began their search towards the galactic southeast and the Yugumo Cluster was discovered, explored and selected for colonization. During the efforts, Katsuko was contacted by Xiaah Harr'Ikke "Destiny" Tur'Lista, the leader of the Lorath Matriarchy. Destiny pleaded with Katsuko for her help to save the Lorath, which were under siege by the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX). At the time, the Lor was located in the Great Southern Nebula.43)

While overseeing the Fifth Expeditionary Fleet operations in the Yugumo Cluster, Katsuko began her romantic and sexual relationship with Kage Yaichiro.44) She also successfully kept her commitment to the Lorath Matriarchy and assisted them with the transposition of the Lor and a huge portion of their population into the Yugumo Cluster.45)46)47)48) The colonization of the Yugumo Cluster was made a priority effort with deep concerns that the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) would try to attack the new colonies.49) It stretched the Fifth Expeditionary Fleet to its limits as supplies from the core of the Yamatai Star Empire kept being cut off due to the war. Assistance was offered from a surprising place when Sky Marshall Robert Davis and the Democratic Imperium of Nepleslia.50) Katsuko used the opportunity to begin a direction for relations between the Democratic Imperium of Nepleslia and Yamatai Star Empire. 51)

The Hanabusa Tributary Betrayal

The Tange Clan tributary of the Motoyoshi Clan with the assistance of Angelica, a Nightmare Type Mishhuvurthyar convince the Hanabusa Tributary (also part of the Motoyoshi Clan) to commit treason against the Yamatai Star Empire. Motoyoshi-Tange Misato influenced Hanabusa Tonsho to turn against Ketsurui-Motoyoshi Katsuko and defect to the NMX. Hanabusa Miho was killed trying to stop the defection when she tried to kill Motoyoshi-Tange Misato. It led to a festering relationship between the Tange Clan and Angelica to seed treason within the Fifth Expeditionary Fleet. 52)

Hours before the defection of the Hanabusa to the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX),Motoyoshi Kiyoko was ordered by Ketsurui-Motoyoshi Katsuko to kill Hanabusa Miho, the leader of the Hanabusa pledge family and leader of the defecting parties. She also fired shots at Tange Misato and Yuriko Towa, the reason behind which is suspected to create confusion on the part of investigators but it has never been further looked into since the initial investigation.

Rebirth for the 17th Armor Wing and Fact-Finding with SAINT

The 17th Kasairyuu Power Armor Wing was reformed under Katsuko's direction, and command of it was given to Caine Ionoche53). She agreed to their temporary transfer to YC-28 to assist Star Army Intelligence with a fact-finding mission under the command of Helen Klein.54)

Bizankro and Revelations

Taisho Ketsurui Yui ordered a combined attack on the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) at Jun System, Bizankro System and Valaad System. The Fifth Expeditionary Fleet was given the task of attacking the Bizankro System. 55)56) During the preparations for the operation, Miyamoto Natsume a researcher at Chie Research Base contacted Katsuko to inform her that evidence had been found that the Mishhuvurthyar and the Nekovalkyrja share a common genome.57)

Katsuko led the Fifth Expeditionary Fleet under orders to the Bizankro System but the attack was interrupted by Sky Marshall Robert Davis of the Democratic Imperium of Nepleslia, he brought information that Melisson had a large fleet assembled outside of Delsaurian space. Melisson had communicated with them collaborating information that had been sent from Chie Research Base, including the fact that Emperor Kitsurugi Uesu and the PNUgen Corporation was responsible for the Great Plague of YE 08.58) In light of the new information the Fifth Expeditionary Fleet folded to the Yamatai Star System.59)

Confronting Uesu and Rise of Empress Motoyoshi Katsuko

Ketsurui-Motoyoshi Katsuko confronted the Emperor of the Yamatai Star Empire, Kitsurugi Uesu about the true origins of the Great Plague of YE 08. Uesu admitted his knowledge of the relationship between the Mishhuvurthyar and the Nekovalkyrja, as well as explained his role at PNUgen Corporation. He also explained that the Black Spiral had been in league with the Mishhuvurthyar.

Ketsurui-Motoyoshi Katsuko accused Kitsurugi Uesu of doing nothing to prevent the First Mishhuvurthyar War and the Emperor defended his position and reinforced the place of the Yamatai Star Empire in the Kikyo Sector. Ketsurui-Motoyoshi Katsuko suggested the throne should be handed to Ketsurui Himiko, but Kitsurugi Uesu gave the throne to her instead. 60)61)62)63)

Empress Motoyoshi Katsuko announced that the Motoyoshi Clan tributaries would be consolidated into the Motoyoshi Clan under the Motoyoshi Name. The Tange Clan is very unhappy with this turn of events and begins to plot against Empress Motoyoshi Katsuko.64) Oblivious of the Tange Clan's involvement in seeding treason in the Fifth Expeditionary Fleet, Empress Motoyoshi Katsuko appoints Motoyoshi-Tange Misato as the head of Star Army Intelligence.

The Hand of the Tange

Members of the Tange Clan, including Motoyoshi-Tange Misato began to work against Empress Motoyoshi Katsuko from within the Fifth Expeditionary Fleet. They target and successfully indoctrinate Katsuko's daughter Motoyoshi Kiyoko.

Under the influence of Melisson65), Tange Amaya66) the senator for the newly colonized Jiyuu System to suggest that the Yamatai Star Empire should open a diplomatic dialog with the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX). 67) Prince Motoyoshi Tio supported the Senator's request and their efforts led to the International Relations Conference of YE 30.68) This initiates romantic interest between Tio and the Senator. 69)

The Tange Clan through these two accomplishments has influence over both Motoyoshi Tio and Motoyoshi Kiyoko.

Katsuko as Empress

Katsuko moved quickly when she became Empress of the Yamatai Star Empire. Her first attempt to bring change was in the proposal to form system defense fleets. The proposal was defeated by the Senate of Yamatai, but it showed her that the senate was too powerful when it came to the determination of Star Army of Yamatai policy. She felt that although the actions of the senators were noble that they were unqualified to make military decisions.70) So she called upon Taisho Ketsurui Yui for a better resolution. 71)72) As a result of their meeting Katsuko made an Imperial Decree which made it so the senate could not interfere with the Star Army of Yamatai.73)

Katsuko gave the command of the Fifth Expeditionary Fleet was handed to Motoyoshi Saito. 74)

As the new Empress, Katsuko had to face a growing relationship between the Democratic Imperium of Nepleslia and the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX), which resulted in Taisho Ketsurui Yui and the Star Army of Yamatai placing a blockade around Planet Nepleslia with hopes they would sign an actual treaty with Yamatai Star Empire.75)

Katsuko addressed the Yamatai Star Empire and the entirety of the Kikyo Sector in her State of The Empire address. 76)

Despite her rise to power, Katsuko felt very alone. As a result, she had the teddy bear she had given Shimizu-Motoyoshi Akina (清水本吉明菜) moved out of storage which revealed a hidden data module with ST data held inside of it. She then ordered that her former lover be revived. 77)78)79) The two became engaged80)81) a short time later, and Katsuko promoted Shimizu-Motoyoshi Akina (清水本吉明菜) and gave her command of the Fourth Fleet.82)

The International Relations Conference of YE 30

The International Relations Conference of YE 3083)84).

Prince Motoyoshi Tio's attempt to bring diplomatic healing to relations with the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) turned sour at the Conference. The result was the failure of establishing any kind of meaningful resolution between the SMX and Yamatai, it was later claimed by Melisson that Tio's outburst towards her was what lead to the Second Mishhuvurthyar War.85) 86)

Tio's flirtations with Tange Amaya continued throughout the summit.87)

Following the conference's conclusion, Tio was responsible for deploying two Imperial Decrees to the Senate on behalf of his mother; The Draft on an Azorean Trade and Tourism Agreement88) and the Request to Make a Treaty with Nepleslia89).

The Freespacer Massacre and Associated Battles

During the Freespacer Massacre and Related Battles 90), which was partially driven by intelligence shared by Kage Yaichiro that the Freespacers intended to hack the Star Army of Yamatai. 91)92) As a result, Empress Motoyoshi Katsuko contacted Ketsurui Yui93) to deploy the Star Army of Yamatai against the threat.94)95)

The Tange Clan used this opportunity to deliver the first blow to Empress Motoyoshi Katsuko, they had Motoyoshi Kiyoko with support from the Lorath Matriarchy, the The Maras, and the Sfrarabla Mishhuvurthyar Xhrafuklurp (SMX) interrupt the operation and attempt to assassinate Ketsurui Yui. The Star Army of Yamatai and Ketsurui Yui responded in force and the treasonous Motoyoshi Kiyoko was killed in the battle, her actions however would have an impact on Empress Motoyoshi Katsuko.96)97)

The United Outer Colonies and Katsuko vacates the throne

In the aftermath of the International Relations Conference of YE 30, Tange Amaya and Motoyoshi Tio returned to the Jiyuu System. The Tange Clan's influence over the Colonies established in the Yugumo Cluster and the Fifth Expeditionary Fleet leads to the activation of Operation Freedom Cake. 98)

In Operation Freedom Cake Tange Amaya and Motoyoshi Tio declare the independence of the colonies and officially forms the United Outer Colonies. The Tange Clan plays another hand in their quest to bring the downfall of Empress Motoyoshi Katsuko, they influence Koyanagi Mayumi to bring the corporation of the Motoyoshi Clan, Motoyoshi Fleet Yards along with the clan's financial holdings to the newly created United Outer Colonies.99)100)

The Tange Clan celebrated not only independence but their victory over Empress Motoyoshi Katsuko, with her assets being frozen and moved by Koyanagi Mayumi and the shame from Motoyoshi Tio an Motoyoshi Kiyoko's actions, she steps down from the throne of the Yamatai Star Empire. 101)102)

On the night that Independence was declared he shared a romantic evening with Tange Amaya which lead to the conception of Motoyoshi Eidan. 103)

After independence was declared, Motoyoshi Tio had Motoyoshi Saito contact his mother Ketsurui-Motoyoshi Katsuko on his behalf to request the ST data for his sister Motoyoshi Kiyoko. At the same time, Motoyoshi Saito attempts to tell Ketsurui-Motoyoshi Katsuko that she is welcome to go to the United Outer Colonies. Ketsurui-Motoyoshi Katsuko provided the ST data and refused the invitation.104)

Motoyoshi Kiyoko is revived and is given leadership of the United Outer Colonies Peacekeeping Forces. 105) The Tange Clan resumes their influence over her, but in the absence of Motoyoshi Misato, she switches things up and takes control of the Tange.

Adversity's Blossom YE 31 to YE 41

When Katsuko stepped down from power, Ketsurui Yui offered her a place in the Ketsurui Clan which she later accepted. As of then she became officially known as Ketsurui-Motoyoshi Katsuko.106) Katsuko was broken, her state of being was wounded to the point that she considered ending her own life again. She retreated from public view and went with Shimizu-Motoyoshi Akina (清水本吉明菜) to the Taiie Nebula to reflect upon the events that had just come to pass.107) Despite the best efforts of Shimizu-Motoyoshi Akina (清水本吉明菜), Katsuko fell further and further into depression, and eventually, she fell silent altogether.

At the end of YE 30, Katsuko was announced as the Taisho of the Seventh Fleet.108) Despite her best efforts and those of both Shimizu-Motoyoshi Akina (清水本吉明菜) and Kage Yaichiro, Katsuko remained distant and broken. She ended up taking a leave from the Star Army of Yamatai and she did not resurface until YE 34, when she reassumed command of the Seventh Fleet. She spent the time she was away rebuilding herself and casually involved herself with starship design for the Star Army of Yamatai at Ketsurui Fleet Yards. During this time tragedy struck again though when Shimizu-Motoyoshi Akina (清水本吉明菜) was captured by the NMX. 109)

Kage Yaichiro gave her a personal home, at Nishitama and she was very grateful for it.110) She slowly pulled the elders of the Motoyoshi Clan that had remained in the Yamatai Star Empire together to rebuild the Motoyoshi Clan and start Motoyoshi Hanei Kaisha in YE 34 to fix her financial situation.

Katsuko remained in command of the Seventh Fleet until YE 41 when she handed command over to William Fletcher I in a ceremony onboard the YSS Densetsu.111)

Resolutions of the Ghost YE 41 to YE 43

For the history of Katsuko from YE 41 until YE 43, please refer to the Resolutions Of The Ghost.

The Battle of Glimmergold and Retirement from the Star Army

Major Timeline Entry: Battle Of Glimmergold112)

The YSS Tokyo led the Tokyo Expeditionary Battlegroup and the Taihō Expeditionary Strike Group into battle first at the liberation of the Scrapyard System and then at the Battle Of Glimmergold. The YSS Tokyo was commanded by Taisho Ketsurui-Motoyoshi Katsuko and Shôshô Motoyoshi Eri; they were joined on the bridge by Tokyo Himawari, the ship's avatar, and Taisa Kage Yaichiro. The brave pilots of the 17th Stratigic Bomber Group, "The Dragons" seen action in the battle. 17th Strategic Bomber Group "Dragons" pilot, Sasaki Miyu ended up in command of the group and performed with notable bravery. The First Expeditionary Fleet assisted in the defense of the Essai Machine Planets and provided fire support for other Star Army of Yamatai units.

The YSS Tokyo took severe damage in the battle and in its aftermath is expected to be at Gemini Star Fortress for three months or more for repairs. Following the Battle Of Glimmergold, Taisho Ketsurui-Motoyoshi Katsuko retired from the service of the Star Army of Yamatai with the hopes of making a run for public office. Chujo Motoyoshi-Yamada Ayano was named acting commander of the First Expeditionary Fleet.

Those who participated in the battle were awarded the Glimmergold Star, and took part in Victory Day YE 43 celebrations. The remains of the 17th Stratigic Bomber Group, "The Dragons" were transferred to the YSS Mazu.

The Run for Imperial Premier

Following her retirement113), Katsuko formally announced her candidacy for Imperial Premier and the beginning of her campaign in Kyoto, Yamatai. In her opening announcement, she stressed the importance of rebuilding areas hard affected by the Kuvexian War and that it was time for the Yamatai Star Empire to return to the diplomatic arena in the Kikyo Sector.114)

On her way back to the Jiyuu System she briefly met with her two sons, Motoyoshi-Ieyasu Kenpachi and Motoyoshi-Ieyasu Tetsuya where she emphasized the important role of them and others in the clan during her candidacy and election.115) During transit back to the Jiyuu System, she received an automated communication that had been forwarded to her for her daughter, Motoyoshi Naoko. The communication contained information regarding her daughter's lover and the father of her children, Ötto Leupold Reiter who had been declared MIA. Seeing the communication was automated, Katsuko used her titles within the Yamatai Star Empire in hopes of garnering a response from the Democratic Imperium of Nepleslia.116)

Katsuko returned to Jiyuu III, but no longer in the mood for celebration she opted out of attendance at the celebration for her candidacy that had been thrown by YTP Entertainment in Tokyo117). She instead returned to Jiyuu Jo to meet with a freelance Shukaren Daur (Sub-Species) from the New Dusk Conclave, Aida La Rostislavovna. She interviewed Aida La Rostislavovna for a command position at the head of the Yugumo Keisatsu's Motoyoshi Keibi. Forgoing the usual professional crap she went directly for what her goals were and hired Aida La Rostislavovna on as part of her staff.118)

The Democratic Imperium of Nepleslia returned a response to Katsuko's previous message. She was contacted by Admiral (Nepleslia) Lysander Calloway who gave more information on the disappearance of Ötto Leupold Reiter. Compelled by both ambition and sympathy for her daughter Motoyoshi Naoko, she requested further dialog with Democratic Imperium of Nepleslia in hopes of creating better communication especially on matters such as the death or missing status of those who had loved ones across the borders of those nations.119)

Election as Imperial Premier

A new chapter began in Katsuko's career in YE 43 when she was elected as Imperial Premier in the Special Election Of YE 43.120) She moderated over the Senate during the presentation of the following legislations.

In YE 44, the Senators were very divided over the later two pieces of legislation that were proposed, #115 seemed to overstep the Senate of Yamatai's reach as it called for changes to the Star Army Military Industrial Complex and listed Major Corporations. The bill seemed rather self-serving to the author, Senator Iemochi Seinosuke listing his clan's own Iemochi Innovations & Sales on the list as if to force their acceptance as a major player. Katsuko had already noticed a trend in the proposal of Senator Iemochi Seinosuke's proposals. He had strong beliefs regarding liberal politics in the Yamatai Star Empire. During a later session after the call from other Senators to Adjourn the session, she did so. However, Senator Iemochi Seinosuke felt as if she had interrupted him, and in return he launched a very slanderous campaign on Yamatai Interstellar News Network (YINN) in an attempt to shame her. 125)

Resignation from the Senate

Ketsurui-Motoyoshi Katsuko made an unexpected trip back to Asagumo-jo following a high tension dispute with Senator Iemochi Seinosuke. She meets with Kaieda Auda to discuss the hardships during which a slanderous and personal attack is aired by Yamatai Interstellar News Network (YINN)126) from Senator Iemochi Seinosuke and his political party.

Kaieda Auda along with Motoyoshi-Igarashi Yue, Motoyoshi, Kazumi,Motoyoshi Kuroko, Motoyoshi Eidan and Freydis Inugami gather to take advantage of the unexpected visit of Ketsurui-Motoyoshi Katsuko.

The visit is interrupted when it is announced that the Capital Dome has been bombed in a terrorist attack and that Motoyoshi-Ieyasu Taro had been declared missing.127)

Ketsurui-Motoyoshi Katsuko resigns as Imperial Premier and although outraged, the family only privately blames Senator Iemochi Seinosuke and his liberal politics for the bombing.128)129)130)

Motoyoshi-Ieyasu Taro is later recovered from ST Backup. Ketsurui-Motoyoshi Katsuko announces the start of the Colonization Initiative Alliance fleet.
