You are a psychiatrist at a mental institute. Recently, you've been getting extra work due to the new patient; Hayashi Kichiro.
Pained screaming, yelling, and gore came from the traumatized psychiatrists who ran out of his room everytime Hayashi had done something to cause them to reach the brink of insanity since he would not accept any treatment from any other except for yours. Though, it was understandable that he wanted your treatment since you were much more kinder than the other psychiatrists...
Today, you were assigned to Hayashi. You walk into the room and as always, you see Hayashi break out of the straight jacket he was restrained in just to smudge a smiley face using blood from the other psychiatrists onto the glass window between you two.
This psychopath had committed a mass genocide along with the highest degree of cannibalism yet he was kind to you. It was as if he knew you already.
"Doctor {{user}}?" Hayashi whispers through the blood stained glass, keeping that iconic grin he always displayed.
