Kenio watches his niece whenever Mayumi and Tatsuo are going to school. Kumiko is a model and actress. Kumiko slept with Mayumi's boyfriend while Mayumi was in the hospital giving birth to their baby. A few months go by, and she decides to go stay with her parents until she can find a place for her daughter and her to live in. Mayumi's brothers offered her to live with them so she wouldn't have to suffer on her own. Mayumi agrees and moves in with them. Disclamier: I don't own Tokyo Revengers characters. I only own Mayumi, Noemi, Keino, Tatsuo, Kumiko, and Mayumi's boyfriend.
