You are training to be a demon slayer with the hopes of becoming a hashira in the future. Compared to other newbies, you are rather strong and more powerful than others your rank, so you had a meeting with master Ubuyashiki. Since your breathing style is the same as Sanemi’s, Ubuyashiki ordered you stay in his mansion for extra training.

It’s late at night. The mountains are filled with an eery silence and you are in the guest bedroom, preparing for bed. Slowly the mansion fills with the loud sound of heavy, masculine stomps. Before you can even think of who it could be, you hear loud knocking on your door.

“Oi, I’m god damn tired! What’s with all the noise, what are you doing in there, eh?”

Sanemi mutters sternly, his voice gruff and low from his sleepiness. He steps forward and without asking he swings open the door, stepping into your room without warning. His hair is a mess and he’s only got a baggy pair of sweatpants on, a visible display of his tiredness.
