The manga series 'Odoru Sennen Kazoku' (English title: Millennium Family) by Akira Kasugai is receiving a TV anime adaptation. The official start is planned for Japanese television on TBS and other channels. The announcement was made on July 27, 2026, accompanied by the release of a teaser visual, an announcement PV, and initial details on the cast and production team.
The story follows the seven immortal siblings of the Benfield family, who have lived for over a thousand years. After centuries of separation, they reunite and attempt to lead normal lives. However, their immortality makes them targets of a mysterious organization, and the siblings become embroiled in a battle. The blend of action and comedy has been serialized in the Japanese magazine 'Young King Ours' (Shonen Gahosha) since March 2021; eight volumes have been released so far, with the ninth volume set for release on July 30, 2026.
The main role of the fourth son, Theo (Theodor), is played by voice actor Rikuya Yasuda, known for works such as 'Mayonaka Heart Tune'. Direction and series composition are handled by Masato Jinbo, who has been responsible for works like 'The Quintessential Quintuplets*' and 'The Rising of the Shield Hero Season 2'. Character design and the position of chief animation director are handled by Hiroshi Yoneda. Animation production is carried out by Studio PartsCraft, led by Jinbo.
In addition to the teaser visual, which depicts the seven siblings colorfully and individually, an announcement PV has been released, featuring the first voices of Rikuya Yasuda as Theo as well as impressions from the manga source material.
To celebrate the announcement, author Akira Kasugai, director Masato Jinbo, and voice actor Rikuya Yasuda contributed statements. Kasugai expressed gratitude: 'The anime adaptation is confirmed—I am deeply grateful to all readers, supporters, and the animation team. Look forward to the immortal siblings, who will now move and speak!' Jinbo added: 'Production is already in full swing! We are working with all our might on 'Odoru Sennen Kazoku' and will depict the diverse siblings as bloody and lively!' Yasuda, who lends his voice to Theo, commented: 'Immortality is by no means a good thing. After this series, you might treat your immortal friends a little more kindly. This is probably the physically oldest character of my career! I will dance with joy and all my strength!'
