Welcome to Demon School! Iruma-kun Season 4 — Bakian's continuing adaptation of Osamu Nishi's manga — landed its episode 8 with the kind of steady delivery that's made the property one of NHK E's longest-running anime cycles. ANN's review covers the episode and the preceding episode 7 review provides the structural context.
Quick answer
Welcome to Demon School! Iruma-kun Season 4, Episode 8 is reviewed by ANN as the show holds its position in its current cour. The franchise has run on NHK Educational TV since 2019, adapting Osamu Nishi's Akuma no Iruma-kun manga (Akita Shoten). On SenpaiRanks, the Iruma-kun franchise sits in the long-runner tier — consistent multi-season scoring with a stable community-vote base. Season 4 is currently airing weekly.
What the episode does
Episode 8 continues Season 4's arc structure — without spoiling specific beats, the cour has been pacing the source material at a controlled tempo. The show's adaptation pattern hasn't shifted across the season; Bakian's production discipline holds, and the weekly broadcast rhythm on NHK E keeps the show in the audience habit-pattern that long-runner franchises rely on.
Franchise context on the SenpaiRanks board
Multi-season comedies often see their per-season ranks plateau after season 2. Iruma-kun avoided that — Seasons 1-3 each landed within a tight scoring band, and Season 4 is tracking similarly per SenpaiRanks's per-episode adjusted scores. The property's combined cross-season rank sits in the mid-tier of the long-runners list, with the back half of the current season as the rank-revision window.
Why the steady delivery matters
Long-running fantasy-comedy adaptations that hold quality past three seasons are rare in the modern slate. The Iruma-kun production model — modest budget, character-driven script, episode-of-the-week structure — is the kind that ages well because it doesn't depend on set-piece animation. The show's Spring 2026 cour is the structural mid-point of the broader run; the ranking signal won't move sharply but it'll keep paying its weekly slot.
