Welcome to Demon School! Iruma-kun Review — The Nicest Kid in Hell Keeps Winning

Picture the worst possible place to be discovered: a school built for demons, where a human classmate would be less a scandal than a snack. Now drop the gentlest boy imaginable into the middle of it. That's the standing tension powering Welcome to Demon School! Iruma-kun, this 2019 series' single joke and inexhaustible engine — Iruma can never say no to anyone, which is exactly how he ended up enrolled in demon school in the first place, and exactly why every episode escalates.

What impressed me most is the pacing discipline for a comedy this size. Twenty-three episodes is a long order, and the show manages it like a good tournament arc manages fights: every gag setup pays off within the episode, while the bigger question — how long can a human pass unnoticed among demons — keeps a low, steady heat under everything. The supporting demons are the real roster depth; the show keeps rotating fresh personalities into Iruma's orbit and letting his sincerity break them one by one, and that formula stays funny far longer than it has any right to.

The fair knock is visual: the production is serviceable rather than striking, and the bigger comedic set pieces sometimes want more animation muscle than the show can flex. But charm covers a multitude of budget sins. With sixteen episodes streaming free here, this is an easy, generous binge — the rare comedy that leaves you lighter than it found you.
