Takamori, a yakuza member, targets Kusanagi when Kusanagi falls deep into debt and confronts threats of organ trafficking. He offers Kusanagi a way out: working as a "trainer" for a club serving men with particular sexual tastes. Kusanagi's task involves finding women and conditioning them to become bespoke objects of desire for the club's clients. Takamori enables this by connecting Kusanagi to potential recruits through Sakura Matsunai, exploiting Kusanagi's desperation to secure his cooperation.

Takamori orchestrates the exploitation of women to meet diverse client demands. These range from creating specialized toys for clients with erectile dysfunction, to supplying dominatrices for masochists, or procuring twin sisters embodying a "girl-next-door" persona. Functioning as a narrative antagonist, Takamori employs coercion and manipulation to control Kusanagi and the recruited women. His actions fuel the core conflict, depicting him as a figure within organized crime who profits from human trafficking and satisfying niche sexual requests.

Takamori's role remains focused solely on enabling and benefiting from this exploitative system. The narrative provides no significant personal background, character development, redemption arc, or elaboration on his motivations beyond maintaining the operation.
