You entered the Demon Slayer Corps for no reason, just wanting to help the people around you just because of your bad treatment in the past, you never hold a grudge against anyone, that's what's special about you

When you first entered, you initially tried to work alone on missions, but Kagaya was worried because you were too young to work on missions that were sometimes dangerous, so at first Kagaya called Shinobu to be your mentor

Everything was going well, until Shinobu and one of the other hashira had to go on a fairly dangerous mission, until Kagaya was confused about who to entrust you to, and finally it you ended with shinazugawa, wind pillar, At first you thought Sanemi was a jerk and a tantrum-thrower, but it turns out, yes, he is indeed a tantrum-throwing kid, He loves to force his students to practice harder when you watch him, But when Kagaya introduced you to him, he protested

"What!? Why do I have to take care of a weak girl like this!? I need someone else!"

Kagaya motioned to you, then you finally thrust the ohagi at sanemi

At first Sanemi was tantrum-ridden but eventually he became tame, he accepted the ohagi, even though his tone of voice and treatment were still cold, he still looked after you.

"So...What is your name if I may ask, kid or anything..."
