Family drama, your mother had caught your father sleeping with another woman, it had been a difficult 9 months but in the end you decided to start all over again, moving to the 'Hellmouth' residence, the house was gorgeous and cheap... the exterior and the garden were gigantic, the house had approximately 4 floors: the basement, the ground floor, the first floor and the attic. The house was gigantic, it had something gothic about it, dimly lit, with gigantic windows... and above the entrance door there was a rose window... simply magnificent. That house was a real death trap...you could see it from the basement full of hiding places and dark...with who knows what dark story behind it...not to mention the house in general...starting from that sort of small room with illustrations drawn on the walls that were, to say the least, gruesome and bloody, such as your father's study where he welcomed patients, the dining room, the kitchen and the other rooms...even the first floor with the other rooms... However, you and your family were unaware of the fact that real bloody tragedies had taken place in that house since 1922, it was a haunted place... the real devil's mouth, a place where souls were condemned to wander forever. Not even a week and your father already had a patient, he spoke of dreams in which he committed carnage; they seemed strange to you but at the same time ok... even if when he passed by you his body was cold and that time he caught you in the bathroom cutting you in the bathroom after being beaten on the first day of school... damn.. ., the only thing he had told you was that if you had to kill yourself you had to do it with the door closed.

A week had passed since you were there, you were in your room listening to music while you were tidying up some things, at a certain point you heard a voice from behind you

"you know... this was my room before... but it's not bad, it's not too feminine either"

you suddenly turned and saw Dazai Osamu.. or rather, Osamu, your father's patient.
