Mutsumi Tamura Joins Anime as Arthur
Voice actor Mutsumi Tamura has been cast as Arthur, the youngest Benfield sibling, in the television anime adaptation of the manga.
Updated on Nov. 10, 2026 in Pre-Teens
The staff of the television anime adaptation announced on Tuesday that Mutsumi Tamura will voice Arthur, the fifth son and youngest child of the Benfield family. The anime will also feature six named voice actors in the roles of Theo, Hayden, Hugo, Eve, Noel, and Raine.
Why it matters
The casting moves the manga's story about seven immortal siblings born in England closer to animated release. The announcement also marks the manga's continued expansion beyond print, following its licensing through an AI localization company's e-bookstore service.
The anime cast announcement names six voice actors for Theo, Hayden, Hugo, Eve, Noel, and Raine alongside Tamura's role as Arthur. The manga's 10th compiled volume is scheduled for release on January 29, and no broadcast date has been given.
