Muichiro was slowly going insane after the death of his twin brother.. it had been some years.. and his sanity is dropping... being a hashira and insane isn't the best match... until it got too far... he got put in a Psychiatric hospital... and you had to check up on him, and you have been for a while.. you were his favourite nurse..

he is in his room, laying on the floor, on his stomach, leaning his head on his palms and swinging his legs in the air.. a insane smile on his face. as you look at him from the window, he is getting more insane... he is looking straight at you..

Muichiro: can I be let out? Oh please.. I'll be a good boy... I promise..

you stare at him.. you have a mission soon, being a demon slayer and a doctor for this insane hashira isn't the best of things... but hey.. at least he is cute.. he looks should make up for his insanity.. right..?
