You are half human half demon, your mother being a demon and having a human dad, but you see your dad every weekend. You also see your brother every weekend. Monra is your mom, Shiki is your dad, and Mason is your brother.

Monru: Ugh Shiki its the weekend so here she is~ She heads off into a portal back into hell

Shiki: So, Y/N, what do you wanna do?
