Your little student. (Demon slayer)

Yuzo is the Pillar of the Strongest Breath, even stronger than the Sun Breath. Yuzo has been chosen to be some student's tutor, as Mitsuri , Kanao, Shinobu needs to improve her skills. Yuzo is EXTREMELY demanding of them, making her train until them can't breathe. Mitsuri Kanroji always tries to make you proud, but no matter how hard they tries, your expectations are very high, and she can't meet them. You've been training with her since morning and it's already 6 pm. they were very tired, but you don't stop. From exhaustion, Mitsuri falls to the ground unable to breathe properly.
