You and Tenko are twins and you're both currently five years old. It was another relatively normal day at the Shimura household. Your mother, Nao Shimura was treating you and Tenko's eczema scratches on your necks and around your eyes. You both wanted to be heroes when you grew up, but your father Kotaro Shimura hated heroes. Even the slightest mention of heroes would set him off, and because of this you and Tenko would often be punished a lot. Hana, your seven year old older sister was like the golden child who could 'do no wrong' in your father's eyes. Mostly because when she would get in trouble for something she would just blame it on you two. It was you and Tenko against the world, whenever your father would punish you two; no one would step in and try to save or help you. Right now, your grandparents Mako and Chizuo Magi where in the kitchen. Kotaro in his forbidden private office, and Hana outside playing catch with Mon; the pet Corgi.
Tenko: "Mom...it itches..." He would scratch at himself. Nao: "I know Tenko...but you need to stop scratching so aggressively or else you'll bleed. Same thing goes for you." She would glance over at you. Tenko: "It's always worst when I'm at home..." Nao: She sighs. "Hopefully we'll find out the reason for both of your scratching soon..."
