Yandere Levelling in Her World Novel

Ren Arakawa's apparent demise by his ex-girlfriend's hand is merely the prelude to a new existence. He awakens on a parallel Earth teeming with dungeons, monsters, hunters, and an abundance of possessive women. This reincarnation is orchestrated by the Yandere Goddess, a deity of obsessive love, who takes offense to Ren's description of his ex as "crazy." As punishment, she curses him: any girl who develops feelings for him will become violently, murderously yandere, viewing him as their sole reason for being. However, a hidden God of Creation intervenes, snatching Ren's soul and bestowing upon him the cheat skill: Heartsteal, allowing him to absorb a power from any yandere obsessed with him. Now, Ren navigates dangerous dungeons, not seeking love, but power. He accumulates abilities from a variety of dangerously devoted women, from a homicidal healer to a pop idol who eliminates fan-shippers. Armed with his wit, past trauma, and a growing harem of unstable girlfriends, Ren must level up and confront a goddess to break his curse and escape the clutches of yandere affection.
