Romelia Senki Reveals Extra Cast and First Promo for Fall 2026

The official site for Romelia Senki has locked its broadcast window. Studio Atra's TV take on Ryou Ariyama's postwar fantasy light novel will run two consecutive cours from October 2026 on Tokyo MX, BS11, Sun TV, and KBS Kyoto, and the first promotional video finally shows the army Romelia raises after the Demon King is gone.

Four new knights ride in with that promo. Shoya Chiba voices Gran, Gakuto Kajiwara is Ragn, Shun Horie joins as Kyle, and Ryunosuke Watanuki plays Otto. They fall in behind Yuna Nemoto as discarded noble Romelia von Graham, Jin Ogasawara and Tomohiro Ohno as her retainers Al and Ray, and Yuuya Hirose as Prince Henri — the fiancé who ends the engagement the moment victory is declared.

Koji Saito is series director at Atra, stepping in for Hiroshi Shirai. Aya Satsuki handles series composition and scripts, Yoshiko Saito and Yuta Otaka design the characters, and Kohta Yamamoto scores the campaign. The plot starts after Romelia helps slay Demon King Zelgis, only to watch her prince walk away; she answers by founding a military force and trying to rebuild a country that winning the war did not actually save.

Ariyama posted the novel to Shousetsuka ni Narou in 2019 before Shogakukan's Gagaga Books picked it up with art by Kodama. Ryou Kamito's manga runs under Mag Garden. Ahead of broadcast, tickets are on sale for a September 12 advance screening of episodes 1 and 2 at kino cinéma Shinjuku, with Nemoto, Ogasawara, and Ohno scheduled to appear.
