IruMafia Edition Anime Sets January 4 Debut With 12 Episodes
The official website for the Welcome to Demon School! Iruma-kun: IruMafia Edition television anime opened on Tuesday and confirmed a January 4 debut on NHK General at 11:00 p.m. JST, a 12-episode run, and the main visual.
Reporting from 2 sources: Anime News Network, Anime Corner.
Why it matters
The spinoff gets its own NHK General late-night slot and a full 12-episode order rather than a short-form or streaming-first treatment, which puts a side story from the main manga on the same broadcast footing as the parent series.
