Synopsis
Iruma Suzuki has settled into life at the demon school—still keeping his human identity under wraps—and, after everything he’s been through, he’s finally found a clear goal: climb the ranks of the demon world.
That momentum stalls when his club is temporarily shut down and he’s assigned to the strict student council. Working under the famously no-nonsense president Amelie Azazel—also a friend—Iruma struggles to adjust to the council’s rigid rules and packed schedule, yet he’s determined to pull his weight and support the rest of the members.
Complications mount when unusual circumstances cause a dramatic shift in Amelie’s demeanor, threatening the council’s standing and throwing the school’s order into question. With chaos looming, Iruma must find a way to steady the situation before it spirals out of control.
Otaku Consensus
Season 2 lands as the rare shounen-comedy sequel that feels additive rather than repetitive, with Makoto Moriwaki’s direction and Kazuyuki Fudeyasu’s series structure turning school routines, rank progression, and ensemble chaos into visible character growth. Critics and fans consistently praise the manga-faithful adaptation and the student council/Amelie material as a sharper, more character-focused stretch than Season 1’s introductory comedy. The main caveat is pacing: at 21 episodes, its light, club-and-campus rhythm can feel leisurely for viewers waiting for heavier fantasy escalation.
Why You Should Watch
Watch Season 2 if you want a shounen school comedy that delivers progress without sandblasting away its warmth. It scratches the same itch as My Hero Academia’s class dynamics and Assassination Classroom’s ensemble energy, but with less angst and more theatrical demon-world absurdity. The appeal is not just “cute characters being funny”: this season makes rank ambition, student council discipline, club identity, and found-family loyalty feel like parts of the same coming-of-age machine. Viewers who like fantasy academies, expressive reaction comedy, and protagonists whose kindness changes the room instead of merely winning fights will get the most out of it. It is especially rewarding as a binge because its 21-episode length lets side characters and school institutions breathe instead of functioning as one-off gag delivery systems.
Key Characters
- IIruma Suzuki
Season 2 makes Iruma compelling by turning his people-pleasing survival instincts into an active form of leadership, letting his rank-climbing goal feel earned rather than pasted onto a comedy lead.
- AAmelie Azazel
Amelie gives the season its strongest character contrast: a famously strict student council president whose authority, vulnerability, and friendship with Iruma become a major engine for both comedy and growth.
What Makes It Stand Out
- 1
Bandai Namco Pictures keeps the adaptation focused on readable character acting and broad comic timing, a good fit for a season driven more by school hierarchy, council work, and ensemble reactions than by nonstop battles.
- 2
The 21-episode run is longer than the modern one-cour norm, allowing the season to cover multiple school-life arcs without compressing every gag and emotional beat into a standard 12 or 13 episodes.
- 3
Kazuyuki Fudeyasu handles series composition and is specifically credited on the scripts for episodes 1 and 2, helping the season re-establish its rhythm quickly before moving into the more structured student council material.
- 4
The music identity is unusually pop-forward for a fantasy school comedy: DA PUMP performs the opening theme, while Amatsuki performs the ending theme, giving the season a bright broadcast-anime personality outside the episode scripts.
- 5
Its tag profile is unusually balanced for the genre: AniList weights School at 96%, Demons at 95%, Ensemble Cast at 82%, Found Family at 80%, Magic at 75%, and Isekai at 70%, reflecting a series that is not defined by a single hook.
Fun Facts & Trivia
- Fun fact 1

- Fun fact 2
- The original manga creator is Osamu Nishi, and reviewers specifically noted that this season holds closely to the corresponding manga chapters rather than using the sequel as an anime-original detour.

- Fun fact 5
- Its MyAnimeList rank of #721 and popularity position of #732 show a rare balance for a sequel: it is both broadly watched and rated highly rather than being sustained only by a small returning fanbase.
