Previously known as UX-6, Kazumi (written 上薬) is a star system between the Samurai Sector and the Ketsurui Military Sector, first explored by YSS Eucharis, which left an Orbital Geological Survey Platform in orbit of Kazumi-II. Positioned in a gap between a large nebula and about halfway along a major Yamataian space lane, the system has a strategic position. Kazumi formerly served as the headquarters for the Yamataian Star Army's Third Expeditionary Fleet.

In YE 36, this system became part of the PAINT public transportation system and has a Tenba that regularly visits and provides passenger flights to Shinjuku Starport on Hanako's World.

In YE 41, during the Kuvexian Invasion of YE 41 (part of the Kuvexian War), this star system fell to the forces of the Interstellar Kingdom Of Kuvexia and was under occupation. During the invasion, a star fortress called Kazumi no Iori was destroyed.

The Kuvexian Navy built a base in the system afterward, which was privatized after the war.

In YE 45, the YSS Resurgence conducted a raid on a ship here.
