Kurama Clan

The Kurama clan is a clan of extremely skilled genjutsu users, introduced in the anime. This talent in genjutsu is due to the unnamed kekkei genkai that the clan possesses. However, once every few generations, a member of the clan will be born with such enormous skill in genjutsu that their illusions can actually produce tangible effects that occur in reality. The clan member's talent in the field is such that their genjutsu is completely irresistible, so much so that only knocking a person unconscious has any chance of awakening them from it. Furthermore, the genjutsu is so powerful that it causes the brain to make anything that happens to the victim within the genjutsu physically real, allowing the clan member to potentially kill their opponents with genjutsu. Such frightening power is not without its drawbacks, however. The user can rarely control the full extent of their abilities, and as such their subconscious will often regulate that power, leading to the creation of a second personality in control of that power. This personality then overwhelms the original, turning the individual into a monster that is a danger to everyone around them. They were originally one of the more prominent clans in Konohagakure, but the number of ninjas in the clan has severely dwindled.
