My Cleaner is the Archmage

At the Academy of Eseria, the primordial archmage Caleb, possessing the power of creation, disguises himself as a lowly dust remover, secretly mending the world's collapsing underlying logic. However, his casual display of absolute power attracts the fervent infatuation and competition of three academy queens—the yandere Shadow Queen Serena, the arrogant pure-blood heiress Victoria, and the wild beast-taming bully Lacey. Faced with the ignorant provocations of the Pure-Blood Elders and the destructive invasion of the Abyss, Caleb no longer hides, suppressing everything with invincible might. Ultimately, for the sake of his bond with these three girls, he shatters his ruthless primordial divinity, choosing to remain by their side in mortal form, becoming their absolute law.
