Takehara, Ryuuzou

竹原リュウゾウ

Akiyuki's father and Fusa's estranged husband. He serves as a local doctor for his community, treating the elderly in the area. He is a slob, and his family frequently visits his office to care for him by handling his cooking and laundry. He prioritizes his work over his wife and son, and was essentially the last to learn of his son's disappearance following the attack on the island. He appears rather despondent regarding his inability to keep his family together. It seems he has a troubled past as a military researcher who worked on humanform weaponization projects, and he now deeply regrets his involvement, which has taken his son from him. He also still possesses Hiruko seeds that he had not parted with, even at the end of his involvement with the military.
