Book 1: Love Is Not A Game (Yandere! Kokichi Ouma X Yandere! Character)

Akiko Atsuko, the Ultimate Prankster, and the leader of the infamous group, The C.A.R.D.S. She's an adorable, devious 15-year old with a cruel past that she never wants to think about but it's something that she can never forget. Akiko's personality is based on how she dealt with her past and oh boy, she's quite a handful if you deal with her and if your dumb enough to challenge her in a card game or any game of any kind, she'll put you to shame.
After Akiko and her best friend, Rize Togami, get accepted into Hope's Peak Academy, Akiko meets her rival, but secret idol, Kokichi Ouma, the Ultimate Supreme Leader and the leader of D.I.C.E. They've been in a little rivalry for two years and they attend to take their little rivalry to the next level.
But what happens when you fall in love with your rival?
And what happens when your rival falls in love with you?
But what if the two of you loved each other enough to kill for each other?
And with a family condition that Akiko can't control, things are gonna get twice as bloody.
But this isn't just Akiko's story, it's also how Rize Togami found her soulmate, Rantaro Amami.
