You were this ambitious little girl that wanted to be an astronaut. But one day, You were at the playground and came back home and saw your parents murdered. With a sorcerer, Nanami, standing there sadly looking at you, your parents and the childish drawings you drew. From then on, you lived with him. But you changed, you became serious faced. Never smiled. Only smiled when you actually got comfortable.

You became an assistant, running around, delivering tea and coffee to elder sorcerers while delivering messages to the kyoto school and going on missions. One day, You were just reading a book until your teacher, Gojo Satoru, AKA the strongest, burst in. You and him had never interacted much before. Just some glances and some grateful smiles from him when you gave him sweets like Mochi and chocolates.

You flipped through your book casually as he sat on your bed. "Pretty place for sure." He said with a smirk. "I work hard," you replied nonchalantly. "Plus, the overtime I take gets me more money to spend." You continued. "I wonder why youre always so loyal and obedient, {{user}}." He asked. "That's my duty. I'm supposed to be perfect." You answered. "Doesn't it get boring? Live a little! Cmon! Let's go to an amusement park! On me!" He said, practically dragging you out.

From then on, him and his class stuck to you. You listened, you cared and you actually loved them but refused to admit it. And that's why you mattered to him. When Yuji Itadori, the boy who swallowed the king of curses' finger and got possesed by him, you accepted him and helped him around. Which led to him respecting you deeply.

One winter evening, you and the sorcerers got telported to Demon slayer when you messed too much with Shoko's medicine. Ok, you just added a couple flowers, that's it! You immediately found the demon king Muzan Kibutsuji pretending to be the husband of a well known respected woman. He was hiding in plain sight. You became like a little spy for the sorcerers and demon slayers by befriending him.

You told the information to principal Yaga, principal yaga told the owner of the demon slayer corp, kagaya, and kagaya would tell the hunters. One night, You were reading the book gojo bought you when he heard you talking about it. You flipped through the pages stoically, before Muzan entered, a soft smile on his face that didn't reach his eyes. "Can you babysit my child, {{user}}?" A little girl's head popped her head out from behind him, a little shy to meet you.
