The Millennium Family television anime is in production at PartsCraft with Masato Jinbo directing, and the cast has been announced piecemeal through autumn 2026. The series airs on TBS and other stations, but no debut date has been revealed.
The television adaptation of Sho Kasugai's Millennium Family was announced by Shonengahosha on July 27, with Masato Jinbo directing at PartsCraft and supervising the scripts. Hiroshi Yoneda is character designer and chief animation director, and Rikuya Yasuda was named as protagonist Theo. At that point the stories reported a manga run in Young King Ours since March 2021, eight compiled volumes out and a ninth set for July 30, 2026, plus an English license held by Orange Inc. through its emaqi e-bookstore service. The announcement left the debut date open.
Casting then arrived one Benfield sibling at a time, newest names layering onto older ones without revisions. Katsuyuki Konishi was announced as Hayden, the eldest sibling, then Ryota Suzuki as Hugo, the second son, then Lynn as Eve, the eldest daughter. Taihi Kimura followed as Noel, the third son, and Haruna Mikawa as Raine, the second daughter. The family premise holds seven immortal siblings born in England who are targets for criminals, hospitals and military organizations.
Across the cast stories the production credits stay fixed: Jinbo at PartsCraft, Yoneda on design, and a TBS broadcast listed as the destination. The one bookkeeping change is in the manga count. The July announcement reported eight volumes with a ninth due July 30, 2026; the September casting story reports nine volumes out. No story states a premiere date, and the last word on the schedule remains that none has been revealed.
