Kouichi is a young man with brown hair and olive eyes, originally from the same farm where Ray grew up. He is identified as Ray’s first love, and a flashback reveals that he once proposed the two of them run away together from their restrictive environment, driven by a wish for freedom and a better life. After Ray was rescued from the farm, Kouichi vanished and remained missing for an extended period. He later reemerges by reaching out to Ray from an undisclosed location, asking to meet her. His personality, as glimpsed in memories, shows quiet resolve and a deep emotional attachment to Ray. His primary motivation is tied to her; the desire to escape with her shaped his early actions, and his later reappearance points to unresolved feelings and a need to reunite. The most important relationship in his story is with Ray, whose past and future are intertwined with his own. Kouichi’s role centers on being the lost figure from her past, creating a blend of nostalgia, longing, and mystery. He does not possess any notable abilities beyond ordinary human traits, and his character’s weight comes from the emotional history he shares with Ray and the unanswered questions about his disappearance and return.
