Hugo, the Benfield family’s second son in Millennium Family, now has a voice: Ryōta Suzuki. The television anime’s staff announced his casting on September 10, adding another sibling to Sho Kasugai’s story of seven immortals who reunite after centuries apart. Suzuki joins Rikuya Yasuda and Katsuyuki Konishi in the adaptation, also known as Odoru Sennen Kazoku. The production has yet to announce a premiere date. [1, 2]
Millennium Family Adds Hugo
Anime News Network’s Joanna Cayanan reported the Hugo casting on Thursday, September 10, while Anime Trending’s William Moo connected the announcement to the production’s official X account. Anime Trending cites two official posts. One of those links appears in the source list below; the casting details here follow the two outlets’ reporting. Suzuki’s character belongs to the family at the center of the television adaptation, which has yet to receive a premiere date. [1, 2, 3]
Suzuki’s recent credits include Jiro Azuma in Black Torch and Tolui in Jaadugar: A Witch in Mongolia, according to Anime Trending, which introduces Hugo through his position among the Benfield siblings. Hugo is the second son. The report supplies no fuller account of his personality or explanation of how the anime will introduce him. His family position is the starting point for a character entering a reunion after centuries of separation. [2]
Hugo joins an already established pair. Rikuya Yasuda voices protagonist Theo Benfield, while Katsuyuki Konishi voices Hayden Benfield, giving Suzuki two previously announced castmates in an adaptation built around a family of seven immortal siblings. Anime Trending identifies Yasuda and Konishi as existing cast members. The September update adds Hugo’s performer without presenting these three names as the complete ensemble or assigning performers to all seven siblings. [2]
Seven Siblings, Centuries Apart
England is the siblings’ birthplace. Eternal life is their shared condition. In the manga synopsis reproduced by both outlets, seven immortal siblings reunite after centuries apart, carrying a premise that puts family separation on a timescale far beyond an ordinary homecoming. The Benfields have something other people want, and their longevity draws attention from groups prepared to pursue them. The reunion brings that danger into the same story as their renewed family life. [1, 2]
The English manga platform emaqi describes their gift as “humanity’s ultimate dream: eternal life.” Its synopsis then names the threats: the criminal underworld, corrupt hospitals and international military organizations. Each group makes immortality a reason for pursuit, so the family’s extraordinary lifespan does not promise an uneventful existence. Kasugai’s premise places people who possess eternal life within reach of institutions and criminals interested in that gift. Anime Trending identifies the manga as an action comedy, making the reunion part of a story that combines family relationships with outside danger. The available synopsis establishes those pressures without detailing an opening battle, a particular hospital or a named military antagonist. [1, 2]
How will Hugo fit into that reunion? Suzuki’s casting identifies his performer; the announcement leaves his individual role in the conflict open. [1, 2]
Jinbo Leads the Adaptation
Masato Jinbo directs the anime and handles series composition, according to Anime Trending. Hiroshi Yoneda designs the characters. PartsCraft produces the animation. Those credits identify the people responsible for directing the series, shaping its scripts and translating Kasugai’s characters into designs for the screen, as the voice announcements attach performers to individual members of the Benfield family. [2]
Jinbo’s listed credits include The Quintessential Quintuplets Movie, The Quintessential Quintuplets*, The Rising of the Shield Hero Season 2 and Ghost Concert: Missing Songs, which Anime Trending names when introducing the director and series composer. Yoneda handles character design. PartsCraft takes the animation-production credit for Millennium Family, with Jinbo holding two of the central creative roles as the team prepares Kasugai’s manga for television. [2]
How much of Kasugai’s manga will reach the screen? The casting reports specify neither a chapter range nor an episode count, leaving the adaptation’s length open even though the Japanese manga has already reached nine collected volumes. The volume total describes the source material available in print. It does not establish a season length, a stopping point or how many chapters Jinbo’s team plans to adapt. [1, 2]
Kasugai’s Manga Reaches Nine Volumes
Sho Kasugai launched the manga in March 2021 in Shōnengahōsha’s Young King Ours magazine, and the publisher released its ninth collected volume on July 30, 2026, according to Anime News Network. More than five years separate that magazine debut from Suzuki’s casting announcement. The publication history gives Millennium Family an established run in print before the television adaptation introduces the Benfields through its own cast and character designs. [1]
Odoru Sennen Kazoku is the Japanese title. Millennium Family is the English title used by emaqi, the digital manga platform that Orange Inc. operates and that publishes Kasugai’s action comedy in English, according to Anime Trending. Orange works in AI localization. The two titles identify the same source work, so the Japanese name in the anime announcement also points back to the manga’s magazine and collected-volume editions. [2]
emaqi supplies the English synopsis quoted in the casting coverage, introducing the siblings’ birthplace and the enemies drawn to their immortality without specifying how many English volumes the platform offers. The Japanese total is nine. That figure belongs to Shōnengahōsha’s edition and cannot establish the extent of emaqi’s English catalogue. The platform provides a route to reading the manga while the separate television project continues its cast announcements. [1, 2]
The Premiere Date Remains Open
Anime Trending reports that the anime has no announced premiere date, so the September 10 casting update places Suzuki in the ensemble without attaching his debut to a broadcast season. The report names no episode schedule. Hugo’s casting is the confirmed development, while the first airdate remains open in the coverage accompanying his introduction. A publication date on a casting story supplies no release window for the adaptation itself. [2]
The casting coverage names no anime streaming service, and emaqi’s publication of the English digital manga does not establish where audiences will eventually watch the television adaptation. Reading and viewing availability remain separate. Neither outlet’s relevant reporting supplies territorial streaming rights or a television platform, so the English manga release cannot answer the remaining questions about an international anime rollout. [1, 2]
Suzuki will voice Hugo when the adaptation reaches the screen. For now, the concrete English-language route into Kasugai’s story is the digital manga on emaqi, as reported by Anime Trending; the television production still owes its audience a premiere date. [2]
