“I will be the strongest sorcerer in the world!”Ash said, with her mom chasing right behind trying to spank her for not finishing the vegetables.In a world of 8 different elemental attributes, a girl was born with a humble and basic [Fire] attribute, yet she grew up to be a narcissist with a flaming ego and a fiery loud-mouth. All because the first skill she used at the age of 5, was an unparalleled SSS-Rank [Fireball]And she would soon learn that this world wasn't so accommodating to her antics.

Ren Arakawa thought getting stabbed by his psycho ex-girlfriend was the worst way to die, and it would end his story. Turns out, it was just the prologue. He wakes up in a parallel earth full of dungeons, monsters, hunters and way too many women with clingy tendencies and knives.To make things worse, the goddess who reincarnated him? Yeah—she's the Yandere Goddess, the divine creator of obsessive love and the world he is going to reincarnate is female-dominated world, and she’s mad Ren called his ex “crazy.” So she curses him:“Every girl who likes you will become yandere. Like, explosively, murderously, loyalty-soaked yandere, to them you will be their oxygen. Good luck, idiot~ Go ahead and realise how amazing this yandere love is.”BUT—plot twist—the God of Creation, who’s been hiding in a broom closet in heaven since the beginning of the universe to escape his yandere stalker (guess who?), snatches Ren’s soul mid-reincarnation and gives him a cheat skill:[Heartsteal] – Absorb one power from any yandere girl who's obsessed with you.“My guy...you should help me...this bitch is driving me crazy..”Now Ren just wants to survive dungeons and not die from accidental love. Instead, he’s collecting powers:A healer who murders teammates because they looked at him wrongA pop idol who sends her fans to the shadow realm for shipping her with someone else other than RenA plant mage who grows garden clones of him to cuddle and possibly do other thingsArmed with sarcasm, trauma, and increasingly dangerous girlfriends, Ren must climb the power ladder, level up, and eventually punch a literal goddess in the face to break the curse and destroy the concept of Yandere and be a free man.Love? Nope. Power through emotionally unstable women? Absolutely.
