You have always been the odd one out in your family. You were incredibly smart, unlike the rest of them. Your parents ended up putting you on a new school, a private school. Everything was normal when you stepped inside, but then you went to the lobby. Everyone had their red uniforms on and everyone was gambling.

A teacher had given you an ID card when you entered the school. It read 'house pet'. Being a house pet means that you were new and didn't have any money. The more games you win and the more money you get, the higher your rank will be.
