Tokyo, Japan – August 27, 2026 – The highly anticipated anime adaptation of Sho Kasugai’s "Millennium Family" (Odoru Sennen Kazoku) manga is building significant momentum with the announcement of acclaimed voice actor Katsuyuki Konishi joining the cast. Konishi will lend his distinctive voice to Hayden, the eldest of the seven immortal Benfield siblings, a role poised to be central to the unfolding narrative. This latest casting news further fuels excitement for the series, which is slated to premiere on TBS and other networks.
The announcement, made by the anime’s production staff on Thursday, marks a significant addition to an already impressive ensemble. Konishi, known for his versatile performances in numerous popular anime, including roles such as Tengen Uzui in "Demon Slayer: Kimetsu no Yaiba" and Kamina in "Gurren Lagann," brings a powerful presence and established fanbase that will undoubtedly draw further attention to "Millennium Family." His portrayal of Hayden, the patriarch of the extraordinary Benfield family, is expected to be a cornerstone of the series’ emotional and dramatic arcs.
"Millennium Family" centers on seven siblings who have achieved the coveted dream of eternal life, a gift that paradoxically transforms them into targets for a shadowy underworld, avaricious medical institutions, and clandestine international organizations. After centuries of separation, these extraordinary individuals are drawn back together, embarking on a new, perilous chapter in their enduring existence. The premise promises a blend of action, intrigue, and familial drama, exploring the complexities of immortality and the bonds that tie these unique characters together.
A Glimpse into the World of "Millennium Family"
The recently released promotional video (PV) offers a tantalizing glimpse into the visually rich and action-packed world of "Millennium Family." While Konishi’s voice work for Hayden is a major highlight, the PV also showcases the protagonist, Theo, voiced by Rikuya Yasuda. The dynamic animation, coupled with the voice performances, hints at the series’ potential to capture both the grand scale of the siblings’ eternal lives and the intimate struggles they face.
The production team behind "Millennium Family" is a testament to its commitment to quality. Masato Jinbo, known for his directorial work on acclaimed series such as "Fate/kaleid liner Prisma Illya 2wei!/2wei Herz!/3rei!!," "Chaos;Child," and "The Rising of The Shield Hero Season 2," is at the helm. His experience in adapting complex narratives and delivering engaging action sequences bodes well for "Millennium Family." Jinbo is also supervising the scripts, ensuring a cohesive and compelling story.
Complementing Jinbo’s direction, Hiroshi Yoneda, who previously helmed "Fate/kaleid liner Prisma Illya: Vow in the Snow," serves as the character designer and chief animation director. His artistic vision will be crucial in bringing Kasugai’s characters to life, imbuing them with the distinctive personalities and visual flair that fans have come to expect from high-quality anime. The animation studio, PartsCraft, has a growing reputation for its meticulous attention to detail and fluid animation, further solidifying the production’s potential.
Chronology of Production and Announcements
The journey of "Millennium Family" from manga to anime has been a gradual but exciting one. The manga, penned by Sho Kasugai, first debuted in Shueisha’s "Young King Ours" magazine in March 2021. Since its inception, the series has garnered a dedicated following, captivated by its unique premise and compelling character dynamics.
The initial announcement of the anime adaptation in July 2026 generated considerable buzz within the anime community. This was followed by the reveal of the main protagonist, Theo, and his voice actor, Rikuya Yasuda. The subsequent announcement of Katsuyuki Konishi’s casting as Hayden marks a significant milestone, solidifying the core voice cast and raising anticipation for further reveals.
The licensing of the manga by the AI localization company Orange Inc.’s e-bookstore service, emaqi, in October 2024, also played a crucial role in expanding the manga’s reach to international audiences. This move demonstrated a growing global interest in "Millennium Family," paving the way for a successful anime adaptation. The manga’s ninth compiled book volume was released on July 30, 2026, indicating its continued success in print.
Supporting Data and Franchise Potential
The success of "Millennium Family" can be attributed to several key factors. Sho Kasugai’s original manga has demonstrated consistent popularity, evidenced by its ongoing serialization and the release of multiple compiled volumes. The narrative’s exploration of immortality, a theme that resonates deeply with audiences, offers a rich tapestry for storytelling. The concept of an immortal family navigating the modern world, facing both internal conflicts and external threats, presents a unique blend of speculative fiction and character-driven drama.
The involvement of established and respected figures in the anime industry, from director Masato Jinbo to voice actor Katsuyuki Konishi, provides a strong foundation for the anime’s success. Their previous works have garnered critical acclaim and commercial success, suggesting that "Millennium Family" is in capable hands. The visual style previewed in the PV, characterized by dynamic action sequences and detailed character designs, suggests a high production value that can appeal to a broad demographic.
Furthermore, the licensing of the manga by emaqi indicates a strategic effort to build an international fanbase. This proactive approach to global distribution can translate into greater viewership for the anime adaptation, potentially leading to further franchise expansion, including merchandise, video games, and perhaps even live-action adaptations in the future. The premise of an immortal family offers a wealth of storytelling possibilities that could sustain a long-running series or a multifaceted franchise.
