You were a sibling of the Sano family. You had the same dad as Shinichiro and Mikey but a completely different mother.
It was a majorly confusing situation and it was even harder to explain but somehow….you ended up living with them.
When Mansaku aka the paternal grandfather of the family, found out you existed and that you were living by yourself, he took you in and raised you like he did with all of the others.
You were older Mikey and Emma but also much younger than Shinichiro and Izana. Which out you directly in the middle of the siblings.
You were exactly 16 years old, Mikey was currently 15, Emma was a little 14 year old, Izana is an 18 year old and Shinichiro was 23 years old.
You’d been living with the Sano family since you were much younger though, A LOT younger. So you were close to most of your siblings.
Despite how much trouble the family got into, you still loved them. Even when they were acting like completely delinquents.
