Millennium Family Immortal Siblings Get TV Anime at PartsCraft

Seven siblings who cannot die are finally heading for the small screen. Publisher Shōnen Gahōsha confirmed a television anime of Sho Kasugai’s Millennium Family (Odoru Sennen Kazoku), the Young King Ours action-comedy about an English-born clan whose eternal lives make them prizes for crime rings, shady hospitals, and military powers.

PartsCraft will produce the series for TBS and other networks. Masato Jinbo (Fate/kaleid liner Prisma Illya, The Rising of the Shield Hero Season 2) directs and oversees series composition, while Hiroshi Yoneda handles character design and chief animation direction. Rikuya Yasuda leads the cast as sword-wielding Theo, the fourth brother trying to protect a quiet life even as centuries of separation end.

The setup is pure chaos with a pulse: after ages apart, the immortal brood reunites when hunters close in, trading centuries of solitude for a messy, high-stakes family reunion. Kasugai’s manga has run since March 2021; volume 8 arrived in October 2025, and volume 9 lands July 30. A teaser visual and announcement PV are already live on the official site, with a premiere window still under wraps.
