This is an Oumasai fanfic. (Kokichi Ouma x Shuichi Saihara) it has a setting and plot similar to Yandere Simulator.

A pregame Oumasai story! ... (And Yandere Shuichi)

this is an au of danganronpa where as shuichi is the mastermind "not" tsumugi. youll see what i mean ----------- i'll help you all, even if it means taking my own life.

------------- He's the Ultimate Detective, right? He's the most trustworthy person here, right? There's no way he's working with Kokichi, right? ... He can't possibly be the real mastermind, right? ------------- Kokichi Ouma always liked to think of himself as the Ultimate Liar-- of course, being the Ultimate Supreme Leader was much better anyway, but still. Most would even say his entire existence is based on lies, or at the very least he's been surrounded by them. So when he finds out the trustworthy Shuichi Saihara is the mastermind, he proposes a deal-- he'll lie to everyone and lead away from any possibility of Shuichi being the mastermind, and in return, safety from the killings. Who would've thought he'd toss his own plan of stabbing Shuichi in the back right out the window himself? Guess being the mastermind's accomplice is more fun than he thought.

"You're mine kokichi! Only mine!~ Students are out in a killing game but mysteriously, one of the masterminds falls in love with a person in this killing game? That person is kokichi ouma. Shuichi would do anything to get this hands on him but what if someone already did?

Ouma has been Saihara's friend through thick and thin and they always stayed by each other's side! But how is he going to tell him that his feelings might be a bit more than a simple friendship.... And what happens behind closed doors.

'He couldn't forgiven me so quickly maybe hes just tricking me hes the supreme leader after all' shuichi said to himself ... but the way the purple haired boy was looking at him with such a lustful sincere look made him think otherwise and then something clicked on his head he had read about this before... he look at kokichi with a smirk and said "Stockholm syndrome" warning: cursing, mental illness, gore, selfharm, rape Non of these pictures are mine

Kokichi ouma suffers from a rare disease called "Hanahaki disease" so he doesn't have much time he needs to know who the mastermind is and save everyone from this killing game quickly specially his beloved shuichi saihara but what if shuichi IS the mastermind? non of this pictures are mine warning: selfharm, depressive thoughts, smut, gore, cursing

After finding out who the true mastermind of the game was, Kokichi Oma was forced to participate in the new killing game along with 14 new students. The 16th student was none other than Shuichi Saihara, the Ultimate Despair Detective.

I won't make it. Mastermind AU. Might include cursing and might include smut/lemon.
