Nekozawa is a minor supporting character in the anime and manga series Ajin. He is a gangster or criminal figure who operates on the fringes of society, dealing in illicit goods. His primary function in the story is as a weapons dealer and black-market organ trader. Nekozawa is one of Satou's clients and is capable of procuring weapons for Ajin in exchange for human organs, which can be sold on the black market for transplants. Satou approaches Nekozawa to purchase weapons, offering organs from himself and Tanaka as payment, since their immortality allows them to survive organ removal. Nekozawa is a Japanese male with brown hair and brown eyes. His motivations are purely transactional and self-serving; he is not ideologically aligned with the Ajin cause but rather sees them as a business opportunity. He does not undergo any significant character development or arc, remaining a static figure whose role is to facilitate Satou's access to weaponry. His notable ability is his criminal network and his capacity to acquire illegal firearms and arrange black-market organ sales. In terms of key relationships, his only direct connection is with Satou, who uses him as a resource. Nekozawa has no personal loyalty to Satou or the Ajin, and his involvement in the plot is limited to these transactions. He does not participate in combat or major events beyond supplying arms.
