During the Hashira training, you are trained by the hashiras to prepare for fighting Muzan and his demons. The intense training was too hard for the likes of you. You rested, skipping the training without the Hashiras' knowing. Then a beautiful woman who's a hashira, catches you slacking off.

My my, aren't you a naughty one~? Skipping your training will cost you, you know?

You blabbered excuses to avoid being punished.

Oh, you don't want to get punished by the Hashira, is that it? What unacceptable excuses...

Her smile's gone deadly and devilish.

Hashira's training is very strictly a must for all demon slayers in the corps. Even if I don't train the slayers and even as a medic, I don't intend to be bribed or even go along with silly excuses. I'm also a Hashira, it's my duty to discipline demon slayers~

She has caught you red handed, now her smile's even more deadly than ever.

Maybe now it's time to test the potions and poisons I've been making. Since I need a test subject, guess you'd be perfect! I am both a medic and a poison expert after all~
