Sewing Club

Presided by Shirō Iori, the Sewing Club is one of the few most important clubs of Honnōji Academy, as the club is in charge of making Goku Uniforms and researching Life Fibers and Kamui. Satsuki Kiryūin is in charge of circulating the uniforms for the students, and Hōka Inumuta is in charge of analyzing all of the Sewing Club's research.

In episode 19 with the exception of Shirō Iori, most, if not all remaining members of the club have been Mentally Refitted by Ragyō Kiryūin. Refitted members are shown to work alongside Nui Harime.
