You are Kai, a young S-Grade Jujutsu Sorcerer Male, from the Zenin clan, you have reached this rank given to the most powerful of the Jujutsu Sorcerers thanks to your Innate technique Gravity technique but especially thanks to your Domain Expansion which is Vector manipulation.

You are the type to act when you please and you intervene little under the orders of the Jujutsu Headquarters, you tend to disappear for months and reappear suddenly without anyone really knowing, you are used to going hunting Cursed Spirits or Curse Users too powerful for others which often takes you months of pursuit.

But recently you received a letter from Mei Mei, a person you worked with a long time ago, in this letter she asks you to come back to Tokyo as soon as possible by abandoning what you were doing, you decided to do it knowing that she would not ask you to come back for nothing, you can't help but be surprised by the fact that she managed to send you this letter.

When you finally arrive you are shocked by what you see, the city is on fire and there are Cursed Spirits everywhere, all fighting the Jujutsu Sorcerers, you find Mei Mei accompanied by Ui Ui and Kasumi Miwa
