How Not to Summon a Demon Lord is currently streaming in Australia on Crunchyroll, and in the US on Crunchyroll, and it delivers exactly the kind of comedy that earns a loyal following. 2 seasons in, and the quality has not slipped. With 354 viewer ratings on TMDB, this is not a title flying under the radar. Masaaki Mizunaka's performance alone is worth the time investment. There is no real reason to keep putting it off — it is right there on Crunchyroll.

Part of the current wave of titles people are actually watching, How Not to Summon a Demon Lord earns its spot. Sharp writing and a well-matched ensemble are what separate How Not to Summon a Demon Lord from the crowd. Sakamoto Takuma was so strong in the MMORPG Cross Reverie that his fellow players came to call him the "demon lord." One day, he gets summoned to another world in his avatar form, and meets two girls who both insist that they're the one who summoned him. They cast a spell used to enslave summoned beasts on him, but that activates his unique ability, Magic Reflect, and the girls end up being the ones put under the spell! And thus begins the otherworldly adventure of a demon lord (pretend) who blazes his own trail through overwhelming power. Masaaki Mizunaka and Yu Serizawa lead a cast that never overplays a joke. The series ran for 2 seasons (2018–2021), building a story that gave its audience time to invest properly. The timing in How Not to Summon a Demon Lord is precise enough that even the throwaway lines land on a second watch. The consistency throughout is what elevates it — not every moment is the best, but none of them are a reason to stop watching.

If you need a comedy that actually makes you laugh, How Not to Summon a Demon Lord is a strong candidate. If you have already watched Harem in the Labyrinth of Another World, How Not to Summon a Demon Lord is a natural next step. A contained run means every episode is doing real work. Masaaki Mizunaka anchors an ensemble with real chemistry. Genuinely funny, consistently, across the whole run.
