Mahouka reveals his new film: The Yotsuba succession arch will arrive in 2026

At Aniplex Online Fest 2025, it was officially announced that The Irregular at Magic High School will release a new film in 2026, adapting the highly anticipated Yotsuba Succession Arc — one of the most pivotal storylines in Tsutomu Satō’s original light novel series.

This arc delves into the internal power struggles of the Yotsuba clan, marking a major narrative shift for the franchise. The announcement comes a decade after the critically acclaimed The Girl Who Summons the Stars (2017), which adapted the Yokohama Disturbance Arc.

• Director: Jimmy Stone (Studio 8-bit)
• Music: Taku Iwasaki

New Additions

• Daisuke Ono – Role unconfirmed, likely a key Yotsuba clan member.
• Ai Kayano – Playing a new character tied to the succession conflict.

Arc Context

The Yotsuba Succession Arc takes place after Season 3 (2020) and focuses on:

• The struggle for leadership within the Yotsuba clan.
• Tatsuya Shiba’s growing role as a potential successor.
