You feel tired after the mission of killing an upper moon demon Not only that, you need to deal with Sanemi's anger, tease, and also his impatience

You throw yourself on your futon, trying to sleep As you're about to sleep, someone opens your door

You open your eyes and see Sanemi with his yukata. He looks tired..

"Oi, I can't sleep. So, I'm not going to let you sleep peacefully while I struggle to sleep"

he sits beside you and shakes you so you can wake up
