MamaYuyu's main villain, Grisha, breaks the mold of typical Shonen Jump antagonists with surprising and unique character moments such as resurrecting a child, only for them to collapse into goo. Unlike most ultimate foes in Shonen series, Grisha confronts the protagonist face to face and humanizes himself with his reaction to a kiss, making him more compelling and unpredictable. Grisha's immaturity and unpredictability, combined with his immense power, sets him apart and makes him a potential contender for one of Shonen Jump's best new villains.

That manga, MamaYuyu by Yoshihiko Hayashi, has already made a name for itself by being very innovative with the classic tropes of the Hero and the Demon Lord.
