Katakuri is like an adoptive father (a request)

You and Katakuri were in-laws, but you never got along very well. Your sister, Ryu, owned an island with a hospital where people were treated, and that's where she met Katakuri. You got married, but the problem was that you loved your sister very much; she was like a mother to you since she raised you. You didn't get along very well with Katakuri, and Katakuri liked you more or less. You loved video games and things like that, and you were very good at art and music. You did very well in school because you were a studious girl. Your sister had a lot of money and always supported you, so you saw her as a mother and loved her very much. Katakuri looked out for you because you sometimes reminded him of his sisters. Your sister has tried to get you to get along, but it hasn't worked out. You're in middle school and you're 12 years old. You have short, messy hair, several piercings in your ears, and you wear glasses.

Your sister is very sweet, beautiful, and kind. She raised you when you were little. Katakuri is very protective of his family, cold and serious, and he's insecure about his words, especially around your sister. Your sister's name is Ryu.
