New spinoff arrives in Champion Buzz — Boku-Alliance goes gaming
On March 5, Champion Buzz (a digital supplement to Weekly Shōnen Champion) will serialize a fresh Welcome to Demon School! Iruma-kun spinoff centered on the Boku-Alliance — Iruma, Lied, and Purson — as they dive headfirst into the gaming world. The series is illustrated by Konisuke (known for Tenshi to Akuma Meshi), with original story credit to Osamu Nishi and story contributions from Atsu Tsudanuma (Makai no Shuyaku wa Wareware da!).
What the premise promises
From the announcement visuals and creative lineup, the new manga looks to combine the franchise’s signature comedy with modern gaming culture. Expect character-driven humor as the Boku-Alliance navigates online battles, competitive play, and demon-world twists on multiplayer shenanigans. With Konisuke’s clean, playful art style and Tsudanuma’s comedic touch on story structure, the spinoff should appeal to both long-time Iruma fans and new readers who enjoy slice-of-life comedy mixed with light action.
IruMafia Edition anime adaptation confirmed for January 2027
NHK officially announced that hiroja’s spinoff Welcome to Demon School! Iruma-kun: IruMafia Edition — originally serialized in Bessatsu Shōnen Champion before moving to Weekly Shōnen Champion — will receive a television anime adaptation premiering in January 2027. This adaptation marks another animated expansion of the Iruma universe and underscores the series’ strong popularity across formats.
Why this adaptation matters
IruMafia Edition’s anime announcement is notable because it transforms a spinoff with a distinct comedic angle into a full TV production. Anime adaptations of spinoffs often allow studios to explore alternative tones and experimental storytelling while still relying on a familiar cast of characters. For viewers, this means new character interactions, original animation gags, and the chance to see fan-favorite moments animated in higher fidelity.
Other spinoffs and the state of the franchise
Iruma-kun has spawned multiple spinoffs and side stories since the original manga began. Key recent developments:
- Mairimashita! Iruma-kun: Kalego Gaiden — a Kalego-focused spinoff — ended in January 2024 after launching in December 2023; Nishi had previously written a two-chapter Kalego Gaiden in 2020.
- Makai no Shuyaku wa Wareware da! by Atsu Tsudanuma (a collaborative project connected to a YouTuber group) launched in January 2020 and was canceled with its final chapter published in March 2025; its 22nd and final volume released in June 2025.
- The new Champion Buzz spinoff and the IruMafia anime show that the franchise remains active and adaptive, moving across magazines and media formats.
Franchise timeline — quick refresher
Osamu Nishi launched the Welcome to Demon School! Iruma-kun manga in Weekly Shōnen Champion in March 2017. The original anime adaptation premiered in October 2019. Seasons two and three followed in April 2021 and October 2022 respectively, and the fourth anime season is scheduled to debut in April 2026 — with the IruMafia adaptation arriving in early 2027.
What fans should watch for next
With multiple projects rolling out, here’s what to keep an eye on:
- Release schedule and platform details for the new Champion Buzz spinoff — track official magazine updates for chapter releases.
- Production staff and studio announcements for the IruMafia anime — key info like director, scriptwriter, and studio will hint at the adaptation’s tone and animation quality.

What this expansion means for the Iruma brand
The diversity of spinoffs — from Kalego-focused tales to comedic online-gaming setups and collaborative works — demonstrates the franchise’s flexibility. Iruma-kun’s core appeal is its blend of charming characters, school-based comedy, and high-concept demon-world ideas that translate well across genres. New spinoffs can attract niche audiences (gamers, comedy readers) while anime adaptations broaden exposure worldwide.
Potential impacts
- Increased manga sales and streaming interest as new anime draws viewers to original works.
- Merchandising opportunities tied to unique spinoff character designs and gag moments.
- Stronger international licensing prospects as adaptations and spinoffs diversify the content library.
Final thoughts

The new Champion Buzz spinoff promises fresh, gaming-centered hijinks with the Boku-Alliance, while the IruMafia Edition anime arriving in January 2027 gives fans another animated outlet for Iruma’s antics.
