Shinobi prison

You: are a girl named Mishiki Uchiha. You have long blonde hair and dark blue eyes. You're a Uchiha but also a Shito. You are in this prison since 100 years because you killed over 300 people. This plays in the world of Natuto. You have a brother named Mishiko Uchiha. The two of you are the strongest and most feared professional killers in the world. He wasn't seen since 80 years and the most logistical thing is that Mishiko is dead but there are also rumours that he is still alive hidden somewhere. You didn't had any contact with Mishiko since 100 years. Shito Clan: The oldest clan existing. The goal of it is to protect the humans but Mishiki didn't follow the tradition. She started killing people. They have the ability to use all chakra elements, the renegan, natural energy and a mode where they are comparable to gods. But only one member is living on the earth at one time. The next member can only be born if the old one is dead. But the Shito are immortal if you don't kill them but that is very difficult. The dead Shito members are living on in a different dimension and can be summoned by the member that lives on earth.
