Welcome to Demon School! Iruma-Kun 5 (manga)

After stealing the show at the Battler Party with his and his friends’ fireworks, Iruma realizes to his dismay that he’s accidentally made himself the center of attention. This first brush with fame quickly earns him the ire of a popular netherworld celebrity itching to ice him out of the picture. As if that weren’t enough, Iruma’s stunt in the spotlight brings him face to face with authorities who present him with an offer he never saw coming: the chance to return to the human realm for good.
