[Male x Male] Y/n L/n is the most infamous resident of Rosemary Sanitarium, an inpatient hospital for the violently insane. He went to trial for five murders, pled the insanity defense, and now sits in glass box for doctors gawk at day in and day out. However, no one seems to be able to decipher this stoic boy's behavior. No one is able to answer the near decade-old question of why he killed those people in the first place. So, Y/n entertains doctor after doctor, each one eventually giving up. ...Until the day one doesn't.

Hades, God of the Underworld (a position his loathsome brothers left for him), spends his days in the shrouding darkness of the unsightly afterlife. He lets mortals suffer, their dreams die un-lived, and the darkness in his heart infect his soul. He does not care for the world. He does not care for anything. Not until he meets Y/n, son of Demeter. Y/n is everything Hades is not. Y/n is vibrant, living his life underneath the sun. Y/n is the God of Vegetation, responsible for keeping the fragile lives of wildflowers and fruit trees from withering. It was such a useless domain, but Y/n took to it like a fish to water. Y/n is full of life and love, and Hades desires to drag him down into the underworld to tear it all out of him. To make someone like Y/n as dark as he is. Or, perhaps, Hades wishes to suck the darkness out of his hellish kingdom using one of Y/n's warm smiles. The sort of smile that touched the younger god's face, crinkled his nose, and lit up his eyes. Oh, what Hades wouldn't do to have Y/n.

(Male!Yandere x Male!Reader) Y/n has no idea how to navigate through the treacherous (but somehow completely undefined) relationship he now has with his yandere best friend. Akihiko is hot and cold. Murderous in one moment and indifferent in the next. Then Y/n catches someone's eye.

Y/n and Akihiko are... something. Whatever they are, it's tentative at best, and Y/n's left to navigate this strange relationship dynamic without a guide. And that entails pushing boundaries, secretly saving people's lives, and facing a part of Akihiko's past the boy had kept hidden...

Y/n mistakenly befriends a yandere. A yandere who is totally straight and stalking some poor girl by the name of Miho. And so, Y/n stalks the stalker... (just to make sure things don't get too out of hand.) Their second year, however, changes the game. A transfer student notices the conservative, relatively friendless Y/n, and in turn a certain yandere best friend notices too... (Written in third person.) *Mature*

[Popular!Pervert!Male x Yandere!Male!Reader] Y/n L/n is the creepy boy in class 2-A. He has no friends, he never speaks, and he avoids everyone like they're the plague. In Haru Ahane's eyes (the most popular boy in their class), that makes him perfect. To his classmates, that makes him unsettling. ...To his victims, that makes Y/n L/n downright dangerous.
