Setup: a groggy Kumano is getting dragged out of bed at a late hour. Her character is fussy about her beauty sleep.
Punchline: “had lots of sex afterwards” (yay).
Why is Kumano’s name is inverted on the bolster — anybody? A pun about the fabric belonging to some drapery? I kind of hope not.
It's a reference to how Japanese was spelled back in the day: backwards. It's referenced in an item you can get in game, a poster from Inazuma with her catchphrase written backwards.
