Hikoichi Tsubasa is a mid-level yakuza boss who runs a loan shark business out of Tokyo's Roppongi District. Being a loan shark, Hikoichi has no issues using any means necessary to make the business strive. When Hikoichi's boss dies, his replacement Gensuke Yozan expects Hikoichi to get himself ready to an executive position and puts him in charge of an elderly care facility run by the yakuza.—Kuutti
