The fourth episode of The Vermilion Mask is scheduled for October 31, 2026 at 5:30 p.m. Japan time on the Yomiuri TV/Nippon TV network, with some regional exceptions. Animation producer HIKE announced the episode information on October 29.
100studio handles animation production. The series began its Japanese television run on October 10, and the announcement schedules a second cour for April 2027.
International fan outlook and trend context — Editorial forecast
The announcement lists Japanese catch-up, subscription and rental services alongside the scheduled television broadcast, giving viewers different distribution routes rather than one universal release arrangement. Editorial forecast: overseas fantasy-anime followers tracking the Japanese schedule may find this distinction helpful because a domestic broadcast time and a service’s viewing conditions are different pieces of information.
An official English-language series website is also listed. Consult the series and each service for current availability; a Japanese service list does not confirm overseas streaming rights, simultaneous access or English subtitles. Episode-preview images and plot text are not reproduced here.
朱色の仮面、第4話は10月31日夕方に放送予定
HIKEは『朱色の仮面』第4話を、10月31日17時30分から読売テレビ・日本テレビ系で放送予定と案内した（一部地域を除く）。制作は100studio。第2クールは2027年4月予定。英語版公式サイトの案内もあるが、国内配信先の列挙は海外配信権や字幕を保証しない。権利表記：©HIKE Inc.／©那波なばな・Dr.Poro・少年画報社／朱色の仮面製作委員会。
定時放送と見逃し・見放題・レンタルの国内配信経路を比較した。日本の放送予定を追う海外のファンタジーアニメファンには、放送時刻とサービス別の視聴条件を区別できる点が役立つ可能性がある、という編集上の予測。
