After a Civil war Kusari now is an Empire again. With the end of this war the emperor was exiled and Kusari became a republic (鎖共和国 Kusari Kyōwakoku ). Kusari is allied with Gallia since the war with the Kingdom of Gallia has ended.
Kusari influence stretches from the distant Tau-31 system to Sigma-19, effectively occupying the entirety of the known lower northern Sirius sector. The Kusari is a small yet expansive house, with significant forces holding the four core systems ( New Tokyo, Kyushu, Shikoku, Honshu) and claims and patrols to many other lesser systems surrounding them. Kusari or the Empire of Kusari (鎖帝国 Kusari Teikoku II) (also the second empire of Kusari or restored Empire of Kusari) is the current title of one of the four original houses in Sirius.
