A scarred boy wearing a hood who posts flyers around town searching for Shio. He is 16 years old. In reality, he is Shio's biological brother.

Born as the son of an abusive father and mother, Yuuna, he was recognized as a child who didn't cause trouble, often worrying about Yuuna who struggled with daily life. After the deaths of both parents' parents (grandparents), and when his father started domestic violence, he stayed at home alone to protect his mother and Shio, enduring his father's abuse, dreaming of a happy life for the three of them. Five years later, his father died, and he tried to reunite with his mother and Shio, but couldn't because his mother abandoned Shio outside. Since then, he has been searching for Shio, who went missing after being separated from their mother. He seems to know the true feelings of their mother, which Shio is unaware of.

He is generally kind and values his family, but occasionally shows a cold and violent side like his father. Due to the daily abuse from his father and the police's indifference to Shio's search, he harbors hatred and distrust towards adults, seeing them as filthy and corrupt. He doesn't like getting close to others and shows a mentally weak side, such as when he tried to run away after being yelled at by Shouko. He refers to Shio, who is untainted unlike himself, as "the moon" and speaks of her as the hope of their family. On the other hand, he tells Shouko that he can't imagine happiness without the three of them together.

He feels indebted to Shouko, who helped him when he was down and out, and opens up to her, encouraging her when she was in despair over Satou, and they exchange contact information. He distrusts Taiyou, sensing "the smell of a tainted adult" from him. After learning from a photo sent by Shouko that Shio is with Satou, he starts carrying a metal bat and even tries to threaten and use Taiyou to get Satou's address, showing he will stop at nothing to get Shio back. However, his trauma from his father's abuse remains, as seen when he vomits after attacking Taiyou, revealing his mental fragility. After the series of events, he reunites with Shio and tries to convince her to come home by revealing their mother's true feelings, but she rejects him and attempts suicide. After Shio survives, he tries to persuade her again but is rebuffed, and is horrified when he sees Satou's image overlapping with Shio's.
