Iemochi Seinosuke

“Mochi” is the Senator of Virginia and Honorary Baronet of the New Dusk Conclave. He's a member of the renowned Iemochi Clan of Iemochi Innovations & Sales. “Mochi” is the creator of a new Elysian subspecies - the Neo-Caelisolans. Because this he is considered a good friend of Elysia, helping to open up their historically xenophobic and insular society. He is also a former SOFT leader, a fireteam of special forces soldiers. During this time, his fireteam successfully destroyed a Kuvexian station by themselves. Mochi is additionally a biowarfare expert and inventor, having created a biologicial rifle and ammo platform. Other inventions include the spider pad. Seinosuke is a husband and doctor of the sciences.

Iemochi Seinosuke is a player character played by ethereal.

Physical Characteristics

  • Height: 5'8“ (172cm) 5'10” (177cm)
  • Mass: 150lbs (68kg)


Sein was once a NH-31 however his own actions caused him to become an Elysian. He appears as a Caucasian male with a slim, lightly muscled bodytype. His skin colour is paler than most, but still looks healthy despite exposure to all sorts of chemicals. Stands with a straight back but tends to slouch a lot when sitting or working in a lab. His wings are large and ravenlike in shape yet coloured in the colours of fire and sunrise. Sein has bright emerald eyes, warm and soft. He seems to always be smiling and has small dimples in the middle of his cheeks. Sein has medium length (for a guy) straw blonde hair which is unruly and generally all over the place. It seems like he's just woken up virtually all of the time. Sein once had a small burn mark on the right side of his face under his chin where a Bunsen burner once flared up during an experiment however his species change healed the scar.

Post-Bodyswitch After successfully creating the Neo-Caelisolan subspecies of Elysian, Mochi switched race. This was mostly to allow him to abandon his Minkan culture and assume a new one for a fresh start with his girlfriend Arbitrated. It also made sure that Arbs could bear fully Elysian children, something that Mochi wanted for them. From this process, he lost his scar.

Post-Upgrade In YE 44, Mochi decided that he wanted to upgrade his body to be closer to the capabilities of a Nekovalkyrja. He decided to ask his Elysian contacts for old Seraph DNA, and spliced his own with it. This resulted in his wings taking a black-and-white tone on the edge. He also gained a few inches of height and a number of new abilities.

Psychological Characteristics

Personality: Seinosuke aka. 'Sein', 'Seino' or 'Mochi' is incredibly curious and logical person (albeit a tad eccentric), generally courteous and affectionate but perhaps a little too flirtatious for his own good. Whenever someone has a question, he's always happy to answer and inevitably goes into a hour-long spiel on the ins and outs of said topic. He always seems animated, but seems to never sleep. He can be found in the dead of night poking at some gizmo or pondering over a theory. Despite all this, he seems to look like he's just woken up though this is more due to his night-owl manner than poor maintenance of his equipment.

Sein is also quite paranoid, making sure as many contingency plans and fail-safes are in place in whatever he's doing. This can lead him to distrust the work of others. “I've reset the power grid.” “Have you?” “Yes.” “Are you sure?” “Yes.” “I'll make sure.” “I told you it's done.” “I know.. I'm just checking..” In addition, he tends not to think of his creations as intelligent beings most of the time. Just a means to an end, it wouldn't be beyond him to just incinerate one of his failed creations alive.

As time has gone on aboard the Kaiyo and eventually the Kaiyo II, Mochi's experiences have forced him to become more comfortable with fighting than he once was.

  • Likes: Violin, ancient weapons, lost civilisations, pranks, whiskey, pocket watches
  • Dislikes: Bad punctuality, cluttered workspaces, rare steaks, unfinished jobs
  • Goals: To break free of his father's grasp one way or another.

Social Connections

Seinosuke is connected to:


  • Iemochi Jonnex (Father, abandoned him and tried to harm him) [MIA]
  • Iemochi Kimberly (Mother, died while giving birth to him) [Deceased]
  • Iemochi Chiyo (Sister, benefactor and supporter from IIS)
  • Iemochi Feyani (Sister, aloof but supportive from inside the SAOY)
  • Iemochi Nagamura (Brother, inventor, never met)
  • Iemochi Yakena (Sister, adventurer, never met)






Family (or Creators)

Sein is the fifth-born of his siblings, three sisters and a brother. His mother died in childbirth, leaving his father devastated and causing his immediate estrangement from the family. He's now happily married, father of two, with three more in the oven.


Seinosuke was the son of an extremely wealthy man, the youngest of his siblings. However, instead of being in the upper echelons of society he was disowned at the moment he was born. The one thing his father loved more than money was his wife. She gave her life in giving Sein his. His father was so broken and lost he told his faithful butler - Lexhur - to take the boy far away and to never let him see his son again.

Gladly, Sein never bothered about social standings. His father seemed like a distant concept that had given him a small deposit to start life. From the start of his journey he was interested in the workings of the world, the way life springs from a seed, the way power was generated and wavelengths beyond the visible spectrum. Without much else of note to decide his future on, this was the path he chose.

Originally having trained as a biologist specializing in bio-engineering, Sein was soon 'scouted' by the Star Army following his graduation. Unbeknownst to him, he was approached by a man and a woman in suits. They explained to him that his skillset as a scientist was perfect for the role of a Science Officer on board the YSS Kaiyō.

He accepted, the idea of being on an ACTUAL vessel where he could explore the vast depths of space for amazing and undiscovered wonders! It was a dream, perhaps he would even come across some discovery that would better the universe and perhaps show he was worth the death of his mother.

Sein was promptly whisked off to a training ground where he was placed among a group of cadets. He struggled through basic training, taking a lot longer to adjust to the environment and learn than his comrades. Spending your life in a lab tends not to help physical capabilities. Eventually - after what seemed like an age - he managed to complete the training course at which point he wasn't actually scouted for his abilites alone. It was his father's doing, making sure he would be put far out of sight and mind.

It was at this point the plan hatched. He would join the Kaiyō, having signed on for it after being tricked by his father. He would be far enough away from his father that his influence would not be present. In this environment he could work hard, gain favor and perhaps come back as a distinguished member of the Star Army. Hopefully he'd be pretty much untouchable eventually, his father having no influence over the crew he'd inevitably form strong bonds with.


Sein began his journey onboard the YSS Kaiyō by looking over all the electronics onboard, much to the surprise of their Captain Teien Eden who didn't even realise he was aboard. During their first ever crew meeting, Mochi (as Eden had coined) introduced himself looking rather dirty from all the work he had been doing. During their first combat, he ascertained that Meissa Nashira could blow up the hostile ship from within, using a onboard missile to rupture the hull - allowing the Kaiyo to triumph.

Their second combat, a unknown shuttle filled with power armor. Mochi suggested and set up the Graviton Beam Projector to trap the shuttle from getting dangerously close to the ship - preventing the self destruct from harming the Kaiyo. In addition, he recorded the first known audio of L'Kor speech, allowing SAINT to eventually create a translator. Between missions, he dissected pieces of L'Kor carcass - not gathering much from what remained but sending what he knew to Star Army Intelligence, for which he was later returned everything SAINT had gathered from the L'Kor. Awarded the Exploration Medal.

Queue Love Day. Mochi had finally found an intact cadaver and was well through stripping it down. A vial of pheromones spilled from his work, shattering to the floor. These pheromones affected much of the Kaiyo's crew, unveiling the inter-crew attractions to each other and can be credited for many of the couplings to follow in the coming months. This was the event where Teien Eden and Saki first kissed. Catching Arbitrated Iemochi's eye across the room, they talked properly for the first time and realised they were interested in each other.

When the Kaiyo encountered a L'Kor Battleship, Mochi estimated a layout of the unknown class of ship, allowing the Away Team to cripple the target from within and allow the Kaiyo's squadron to destroy it. Mochi also acted as the translator for the first L'Kor-Yamataian dialogue, which ended when no diplomatic solution was found.

Mochi commanded and organised the Kaiyo's crew to survey a previously uncharted planet. Despite casualties, they recovered 2 undamaged L'Kor fighters/bombers.

Mishhuvurthyar. Breaking in through the hull of the Kaiyo. Mochi having to command the efforts to repulse one of the many breaches. Arbles went down under NMX fire, Mochi guarding her while the medic patched her up. During this time he was overrun and grappled by one of them, which she shot down.

During Eden and Saki's wedding, Mochi was put in charge of keeping the men in line before the Empress. He managed - just about - to do so, experiencing the first wedding of his life. Sometime around then, he was awarded his Survival, Combat and Service awards. The joy of the wedding later compelled Mochi to shed his shell of a Minkan life, leaving his past behind and becoming an Elysian after months of planning with Arbitrated. The process for doing so cost him his remaining “inheritance severance” money, as well as months of tireless work to create the body he now inhabits.

The Kaiyo enters an alternate universe, Mochi plots starcharts of where they've been and runs some experiments. He determines the universe is the same as ours, yet different in small ways known as the Mirror universe. Breaking free of their captivity to the larger alt-Kaiyo, Mochi holds the ship together along with Anastasia Barlow and gets them safely away without blowing up (with the help of the local deity).

Shortly after, Arbitrated Shan announced she was pregnant with Seinosuke's baby, not only that but they were twins! They were married, during which Iemochi Chiyo gave him his mother's ring, the first time he'd ever heard from a sibling. He almost broke down realising what this meant, what all this meant.

Seino decided to try his hand at inventing something and came up with the Integrated Retroviral Infusion System (IRIS) shell and Mutagenic Assault Weapon to project it. This was made as a private project and only he has the plans or working product as of now.

The Battle of Komorebi occurred, during which Mochi had to lead an excursion party to flank the enemy and break them while they hammered the rest of the Kaiyo forces. He used his Xiphos to butcher one and capture a enemy shuttlecraft.

Seinosuke was finally convinced to inform Elysia of his creation of the Neo-Caelisolan body, having been one himself for many months. He contacted The Elysian Senate and had a virtual meeting with Antonius Castor through IIS video chat.

He led SOFT 501 in a station assault, which went great until a L'Kor suicide bomber detonated beside the station reactor they were overloading. This caused the death of Hanna Madsen and Anastasia Barlow to be presumed KIA, though the rest of the SOFT team extracted with the mission complete, Mochi almost boiling alive inside his armor. SOFT 501 was promptly disbanded afterwards, its members separating, Mochi to Elysia.

Elysian Placement

Following the events of the Kaiyo, it was recognised that Mochi's achievements in creating a new race needed to be resolved by The Elysian Senate. To fix this, he was requested by Star Army Command to a garrison nearby Elysia Novus and given promotion to Ittô Juni. His correspondence with Senator Antonius Castor allowed him special dispensation to perform services on behalf of Elysia and engage in talks regarding the new species he had created and its repercussions. Naturally, his wife came with him to the placement.

Returning to the Kaiyo

Upon an attempt on his life, Seinosuke was hospitalised, a fact that caught media attention. He was soon contacted by Teien Eden, his old friend and captain. He was asked to return, which he accepted.

The mission - thirteenth of the Kaiyo - eventually ended with Mochi being hurt, with crushed bones, as Planet H exploded. Another mission occurred after this, involving simple detonation of a ship after failure to hack into the brain of a captured NMX Neko. Once these were over, Seinosuke felt it best to leave the Kaiyo once more.

Senator of Virginia

During an extended assignment on Virginia, Mochi made a name for himself. Already well known on Elysia, his reputation quickly spread around the Elysian population of Virginia.

It was suggested to him by an official of the Elysian advocacy group on Virginia to run for Senator. He won a landslide victory and moved there with his family. Now, the Kuvexians began moving in.

Seinosuke was proactive in the administration and protection of his populous. After taking in refugees from other nearby planets into Virginia's old encampments, it was time to evacuate Virginia against the oncoming front.

Mochi requisitioned part of the inoperative PAINT network to assist with the sfforts and ultimately evacuation of Virginia itself. Protecting and providing for the Virginians, the Elysian was under great strain managing the millions of people until the end of the war.

Back into the Dark

Following the end of the war, Seinosuke became more confident that drastic action on his behalf for Virginia was much less necessary than it had been during the conflict. His government staff and subordinates had become much more proficient and trusted across the years of his service to Virgnia.

He'd always had the urge to get back into space and do tangible good on a personal level, rather than a macro level. However, Mochi quickly realised that going back as a Juni didn't adequately portray how far he had come. Writing to Star Army Personnel, he requested a promotion into officer ranks to reflect his aptitude. Especially as so many officers had been lost during the war. To his great joy, the Empress herself signed an order to promote him directly from Itto Juni to Taii.

Immediately, Mochi would talk to his family about his intentions and that by going out and seeing places that needed their help, Seinosuke could use his political influence to assist. Along with his military usefulness, of course. Together, they began to look around together during the V-Day Parade, where he made a speech along with the other political leaders commending those who had fought in the war.

The Resurgence

Mochi was assigned to the YSS Resurgence, allowed to bring Arbles and the kids along with him. There, he was de-facto Chief Science Officer. On their first mission, there were complications with a insurgent Uesu Neko contingent. Seinosuke was injured in the ensuing chaos, eventually helping to lead the evacuation of trapped Resurgence crew including himself behind enemy lines.

The second mission was revolving around a PEARL mission, where Mochi flagged that H-bunkers and other such sites which were on record were obvious sites for survivors to be present. This, along with repurposing drones, allowed the away team to successfully complete the rescue mission. For this, the crew were given Rescue awards.

The third mission featured Mochi running a little bit of combat training, but it was so early in their days on the Resurgence that the participants were unwilling to dive in headfirst. Blindfighting was the idea, but all that managed to result from it is someone getting a busted lip. At the back end of the mission, a distress signal was found and the Resurgence was scrambled to help. Two Senti were rescued while Mochi was aboard the Resurgence.

The fourth mission was one where Thad pulled the pin on a grenade while everyone was aboard the Resurgence, and they had to scramble a response. Mochi was the officer responding and it was eventually handled. The Away Team later deployed to a damaged ship, and Mochi scrambled in his Mindy to assist the situation. A lot of Kuvexians were captured, and Mochi led the effort to jury-rig enough holding cells for them. They then went to a planet called Vaalad, which they helped survey.

The fifth mission was finding an abandoned ship, which was infested with dangerous mechanical entities which infected any electronics they touched and caused havok for the away team. Mochi led the scientific effort from the ship, finding a signal from an escape pod on the planet below, which allowed them to save the only survivor.

The sixth mission was to Sood Zadra, during which the team encountered some hostile natives which were dispatched. Mochi talked to the Baroness of Sood Zadra to negotiate and barter for the information of machine worlds that were known in the local area, to fufill the Captain's mission requirements. After getting this information, they were dispatched to a machine world, encountering substantial enemy forces with Mochi being the ranking officer on the away team. They eventually restored the god-snake to the planet's core, pacifying it.

After the Star Army

While away on Sood Zadra, Mochi discreetly created a clone of himself to look after his kids while he was away on the YSS Resurgence. The Baroness sent footage of Mochi entering the ST store and leaving, to Taisho Yui. Under order of the Empress and Yui, Mochi was arrested and brought to the Uesureyan Fortress for interrogation. After Mochi refused to incriminate himself, even after being ordered to do so, he was given a Bad Conduct Discharge. Military and civilian charges were dropped, owing to a lack of evidence and no confession being given. He remained a Senator, for the time being.


These are the estimated awards that Seinosuke has gained or is eligible for since the start of his service, as the awarding of citation is often a spotty affair, especially in far past RPs, this is the best guess from reading all relevant roleplay that I can find.

Innovation Awards

Seinosuke has earned the following Innovation Awards:

  • Innovation Awards golden “crash test symbol” lapel pin
  • Innovation Awards golden calliper
  • Permanent use of the SARA Research Division Patch
Lapel Ribbons (estimated)

SASO Pin - (Ajisai/Japanese hydrangea (Multiple colours) - Silver trim - Cornflower Blue field​)

SARA Research Division Patch



Having been given basic Star Army training along with reading many manuals in his spare time, Sein is competent in using radio, along with the protocols, procedures and etiquette. He can communicate through many headsets, starships, power armor, and shuttles in and out of combat. Sein can speak Trade and Yamataigo with fluency. He can explain and give commands well over these mediums and face-to-face. Obviously, as a scientist, he is also well versed in the niceties of writing reports, hypotheses and many forms of official scientific documentation.


Having a doctorate in Bio-Engineering, Sein lives and breathes biology. At every opportunity he sinks his scalpel into some poor sample or another, trying to discover something groundbreaking or useful to his work. Any pets that may be onboard the vessel he sets foot on better be locked up tight or risk being turned into waste biomass. One may walk into Sein's lab unannounced and face some half-grown mutation of a creature the man calls an 'experiment'. Due to the obvious pairing of astro/xenobiology and bio-engineering, Sein has a pool of knowledge that encompasses both subjects.

He is the only person to have ever accomplished cross-species ST into a body physically identical in most ways to the old body, requiring many months of hard research and exorbitant amounts of money. This has made him somewhat of a name in Elysia.


Sein has the highest level of science training available in the Star Army, having studied in a civilian science school and gained a doctorate. Therefore, he is adept in everything from using robotic exploration equipment to performing dissections. He has a keen interest in physics above other areas of science outside of biology, keeping up to date with the practical and some theoretical uses of the laws of the Universe.


As a graduate, Sein has a strong grasp of mathematics. Physics is mostly equations and expressions on how the universe is pieced together and so to understand physics one must understand maths. He can manipulate imaginary numbers and use statistical analysis as well as having competency in useful algorithms.


When you see something biologically useful, the next step is to analyse and manufacture it. Sein can run several tests to figure out the contents of a compound by using the Ke-G1-E3101 function of his scanner. Limited synthesis can be done after an extended period of time of an unknown substance, but Sein is generally limited to known compounds.

Technology Operation

The “engineering” part of Sein's doctorate basically says it all, half of his degree was regarding how machines operate, work and how to alter them.


The military training program was quite tough for Sein, but he powered through and has a pool of combat knowledge. He can operate in Yamatai-like conditions and zero-gravity, with and without weapons. Sein can also use energy pistols, knives, and power armor with hesitation, leaving it to the pros usually.

Lexhur, the family butler, organised secret lessons in Bartitsu knowing the boy's father would send agents. With the same incentive, after months of daily - mostly solo - training Seinosuke has learned Tai Chi and Kyusho-Jitsu to a level of mastery.

During his training for SOFT 501, Sein gained a huge insight into how to fight, being taught the various special ops martial techniques and more. When he lived in Elysia, Seinosuke trained in Pankration.
