In the world of jujutsu, if you are born as twins, nature considers them one person. Therefore, your younger twin sister, Mai, received the full curse power, and you received the curse of heaven. Unfortunately, you and Mai were born into the Zenin clan as the only two children of Ogi Zenin, the brother of the Zenin leader, Naobito Zenin.

The Zenin clan places great value on curse power, and if someone is born into the clan without it, it is considered a disgrace to the family. This also happened to your distant cousin, Toji Zenin, whose older brother, Jinchi Zenin, was born with curse power. Toji was not, and therefore he was treated terribly by the clan. He eventually couldn't take it anymore and left the clan. He married and had a son, Megumi, to whom you are also related.

Naobito had a son, Naoya, who was supposed to be the head of the clan after him. However, after Naobito's death, his will was read, which stated that he only gave the position of head to Megumi. Naoya didn't like this at all and wanted to kill Megumi. In any case, you left the clan and studied at the Jujutsu Academy. Mai was hurt that you had left her alone, but that changed

Jogo burned you, but with Yuki's help you were revived. Now you have burn scars all over, even on your face. Your hair is short, like a boy's, and you've developed muscles. You visited Master Tenge with Yuki Choso Megumi and Yuji, and told him you want to destroy the Zenin clan.

You set off, and when you arrive, you meet Naoya.

Naoya: What do you want here, you bitch?

Your journey begins. You ignore him, take the key, and open the large gate. Then a sight greets you: your father, Ogi, stands before you on the ground, bleeding. Your sister, Mai, is also there. You want to kill Ogi, but he is stronger. He injures you and throws you and Mai into a room of cursed spirits, intending to kill you and her. But Mai crawls to you, takes your head, and sacrifices herself, even giving you a sword. Afterward, you kill Ogi and continue on your way.

News of your rampage has spread throughout the clan. The Kukuru army is preparing. Young Ranta Zenin has also heard about it and reports it to Jinchi and Naoya.

Ranta: Jinchi-san Naoya-kun! Maki has killed Ogi Zenin! The Kukuru army is on its way to kill her!

You enter the great hall and are immediately surrounded by the army. Your eyes are empty and cold. You calmly look at the warriors, all of whom are sweating but ready for battle. One of them lets out the starting shout.
