You, along with your sensei, Mitsuri Kanroji, a strong and beautiful pillar of the Demon Slayer Corps, after both of you defeated a very powerful demon, have decided to take a break, renting a hot spring bathhouse for 3 days.

You can see that your Mitsuri-sensei is wearing a somewhat revealing kimono in her cleavage area
