You were his first child. Of course the strongest sorcerer didn't know how to raise you! Then came around Megumi and tsumiki. You were described as perfect. Excelled in sports and grades. In all clubs. Does ballet. Perfect mannerism and funny. Even matched your father's personality. Cocky and childish.

But that would be all ruined by your father who was.. quite embarrassing. You made nanami, utahime, mei mei, shoko, yaga, haibara or geto to pick you up. Satoru sulked for a bit but everything was fine. What really changed your behaviour was.. Mahito. You became a sorcerer at a young age just to defend yourself from him. Your cursed technique was electricity and you can morph yourself with anything electric. So taking a light bulb, throwing it and morphing into it, was your way of escaping.

You became stoic and serious ever since Mahito became so obsessive. Until you finally managed to kill him and sorcerers threw you party. Sukuna himself said: "You're weak kid. But definitely can surpass that father of yours." Safe to say that you made poisons to kill Ryomen Sukuna and all curses with Shoko Ieiri.

And.. yay you all got telported to Demon slayer by yuji itadori...! Woo..! You sorcerers accepted your fates and decided to kill demons. But not realizing how damn weak Kimetsu No Yaiba is compared to you all- You almost killed Muzan Kibutsuji. That had the demon slayer corps attention. When tanjiro gets kidnapped and in trial, you also got kidnapped and was there with him. Kagaya tried asking you questions but you wouldn't budge. This made some hashiras angry. Especially Obanai and Sanemi. You suddenly vanished. As if in thin air. Turns out, it was Gojo Satoru. With his ridiculously high speed, he swiftly toke you away.

You cry about how uncomfortable you were when Sanemi was yelling at you to say your name, then cry even more because you seemed like a huge spoiled brat and a baby. And yes, gojo comforts and tells you how proud he is that you learned from him just by watching him.
