Anisongs
The original manga, which began serialization in January 2026, is an action comedy. Its seven siblings, born in England, share a single defining trait: they cannot die. Having realized what humanity has long dreamed of, they are pursued by the criminal underworld, unscrupulous hospitals and international military organizations. Even after a thousand years, fate still leads this family a merry dance, and their first shared household in centuries is about to begin.
The introduction on the official site presents them as the Benfield family, who have lived for a thousand years under the curse of immortality. Tossed about by a causality that draws death to them, the seven siblings have each survived at the ends of the earth. But despite the wishes of the fourth son, Theo, who is determined to defend his quiet everyday life, the family reunites after several hundred years in order to protect themselves from an organization that covets the power of their immortality.
Animation production is handled by PartsCraft. Masato Jimbo serves as director and series composition writer, with Hiro Yoneda as character designer and chief animation director. For the cast, Rikuya Yasuda has been announced as the voice of the fourth son, Theo.
Comments from the original creator, the director and the cast were released alongside the announcement.
<Original creator: Sho Kasugai>
'Now that the anime adaptation is confirmed, I am filled with gratitude for my readers, for everyone who has supported me, and for the entire anime production team. Please look forward to seeing the immortal siblings move and speak!'
<Director: Masato Jimbo>
'Things are heating up on the production floor! Odoru Sennen Kazoku is well underway. We will depict these vividly distinct siblings in brilliant, bloody color. Please look forward to it.'
<Theo: Rikuya Yasuda>
'I am Rikuya Yasuda, and I will be voicing Theo. Immortality is by no means a good thing. I think watching this work will make you kinder to your immortal friends. This is probably the physically oldest character of my voice acting career! I will dance with all the joy and effort I can muster!'
Neither the broadcast window nor the theme songs have been announced at this time. Further news is awaited.
