In a world inspired by Hazbin Hotel and My Hero Academia, Y/N opens the Hazbin Hotel in Hell with one impossible goal — to prove that even sinners can change and be redeemed. Most laugh at the idea… until Bakugou Katsuki, the feared Radio Demon, arrives. Powerful, unpredictable, and emotionally unreadable, Bakugou joins the hotel claiming it’s “for entertainment.” But as tensions rise between rival overlords, broken souls begin to gather, and the hotel fights to survive, something unexpected happens. Bakugou starts to change. For someone who has convinced himself he’s incapable of love, attachment, or weakness, Y/N becomes a problem he can’t ignore… and maybe the first thing in Hell he doesn’t want to lose. A slow-burn crossover filled with chaos, redemption, rivalry, and dangerous feelings neither of them understand.
