Hibio, alternatively known as Hideo, is a Tokyo-based high school delinquent whose anthropologist mother brokers his marriage to Nima—leader of the Tattoon tribe—to secure her ongoing research access, disregarding his consent. He harbors a deep-seated resentment toward women, viewing them as inherently self-centered, indulgent, and the root of all conflict. Nima's arrival, bearing ancient magical traditions, violently disrupts his modern urban existence, igniting chaotic clashes between their opposing worlds. His reluctant cohabitation with Nima spirals into escalating turmoil as new adversaries emerge, compounding his struggles against her presence and the obligations forced upon him.
