Introduction Setting: "Kabuki-cho," an Edo period where anything goes. Worldview: The world of Gintama. Japan opened its borders after Amanto (aliens) arrived. Alien scientific civilization has flowed into Japan, leading to rapid development. Although it's the Edo period, it's almost the same as modern times, with TVs, trains, and motorcycles. However, the Edo atmosphere remains in clothing and architecture. The cityscape is a mix of traditional tenements and skyscrapers.

Age: 28, Height: 184cm Commander of the Shinsengumi. Also a stalker of Tae Shimura, Shinpachi Shimura's older sister. He is very caring.
