The joke is that Iruma tries so hard to be invisible in demon school, and every single attempt to lay low explodes into him becoming more of a legend. The comedy timing is genuinely sharp, built on character moments that land harder because you actually care about these people. A cowardly kid surrounded by demons who genuinely love him, accidentally becoming the guy everyone respects.
Iruma's life hits rock bottom when his parents sell him to a demon for cash. Instead of meeting a gruesome fate, he's adopted by a surprisingly kind demon grandfather who happens to be principal of the underworld's most prestigious academy. Now Iruma has to blend in at a school full of actual demons while hiding his human identity, a task made exponentially harder by his complete lack of courage and magical ability. What starts as pure survival instinct becomes something unexpected. Iruma discovers that despite his terror and incompetence, he has a knack for connecting with people, demons included. His genuine kindness stands out in a world where status and power usually matter most. As he stumbles through classroom adventures and befriends an unlikely cast of supernatural classmates, Iruma begins to realize that maybe being weak doesn't mean being worthless. The show balances comedy with genuine heart, watching a cowardly human boy find unexpected strength not through magical power-ups, but through being authentically himself in the strangest possible circumstances. It's about belonging somewhere you were never supposed to be.
