Odoru Sennen Kazoku casts Mutsumi Tamura as Arthur, the youngest immortal Benfield

The immortal family is getting bigger on screen. The official site for the TV anime of Odoru Sennen Kazoku (known in English as Millennium Family) has revealed that Mutsumi Tamura will voice Arthur, the fifth son and youngest of the Benfield siblings.

Who Arthur is

Arthur looks like a kid, but like the rest of his family he has been alive for centuries. The official profile paints him as calm, sharp and the one who quietly fixes the family's messes behind the scenes, with a cheeky little-brother streak on top. Tamura teased that Arthur also carries a special ability, which explains a lot about how unflappable he is, and that he hides more feelings than he lets on. She also joked that this is a show where people lose their lives very casually, yet it stays warm and full of family love. A short character PV went up alongside the reveal.

The cast so far

Arthur joins a lineup that has been rolling out one sibling at a time since September:

• Rikuya Yasuda as Theo, the fourth son who just wants a quiet life
• Katsuyuki Konishi as Hayden
• Lynn as Eve
• Ryota Suzuki as Hugo
• Taihi Kimura as Noel
• Hazuki Mikawa as Raine

Staff and broadcast

Masato Jinbo directs and handles series composition, Hiroshi Yoneda designs the characters and serves as chief animation director, and PartsCraft animates. The series is set for TBS and other channels; an air date has not been announced yet.

Sho Kasugai's manga runs in Shonen Gahosha's Young King OURs. I like how this one mixes slapstick with genuinely bloody action, and the drip-feed of sibling reveals has done a good job of selling the family dynamic. Hoping the premiere date is next.
