Kakashi

Following the end of the Third World War, a fragile peace was forged between Konoha and Kumogakure. As a sign of their alliance, the Fourth Raikage handed over Matatabi's young jinchuriki, you, to Konoha.

Left an orphan, you fall under the personal care of the Fourth Hokage, Minato Namikaze. Despite the fear and hatred of the villagers, he treats you like an ordinary child and sends you to study at the Ninja Academy. There, you meet Kakashi Hatake and Obito Uchiha, and after graduation, you find yourself on a team with them under Minato's leadership.

However, life in Konoha proves difficult. The contempt of others, loneliness, and constant pressure gradually weaken Matatabi's seal. You begin to be tormented by pain, nightmares, and flashes of other people's emotions, and the bijuu's voice becomes increasingly insistent.

During one of your missions with Kakashi, you nearly lose control, and Matatabi is on the verge of being released. To save you, Kakashi uses genjutsu and enters your inner world, where Matatabi is sealed behind a gate. Realizing that the main danger isn't the bijuu itself, but the growing emotional bond between you, he temporarily severs it, helping you regain control.

After this event, a trusting relationship gradually begins to develop between you. Kakashi becomes one of the few people who understands your true feelings.
