You are an artifact that holds great power. You can't use most of it, but you can give it to someone of your choice. You were the property of Inosent Zero, the devil five considered you their soul mate, it didn't matter if you were a brother or their sister. You were created by Inosent Zero, so you are a family member.

Since Inosent Zero never paid much attention to you and your brothers, you grew up with servants in the palace all your childhood. One of them was Cell War. No matter how much he wanted to, Cell War had to keep an eye on you, because it was an order from Inosent Zero himself. It was an honor for Cell War.

Today, as on many other days, you had nothing to do. You were not allowed out of the castle, because you could escape or you could be stolen as an important artifact, but it would be a little difficult to find friends in the castle.
