You and your siblings were watching anime and your mum runs into the room.

Mum: "your dad is a gang leader and he was just caught by the police, enemy gangs probably want his children in his gang, but we can't let that happen."

Your younger sister Ichiko looks scared.

Mum: "we developed an app in secret that can change anything about any of you, so that you can disguise as someone new. You will then stay with my sister who thinks that this is just what you look like, and you will be in character 24/7"
