Major Cast Expansion Revealed for 'Legend After 10-Year Last Stand' Anime Set for 2026 Debut

Anticipation is high among fans following a significant production update for the highly awaited television adaptation of Koko wa Ore ni Makasete Saki ni Ike to Itte kara 10-nen ga Tattara Densetsu ni Natteita, known internationally as I Became a Legend After My 10 Year-Long Last Stand. As the scheduled 2026 premiere approaches, this recent announcement confirms the addition of a new voice acting duo. This move signals that Studio Gekkou and GREE Entertainment are meticulously expanding the series' extensive character roster.

The narrative centers on Rakku, the Hero's former mage. He spent a decade in solitary defense against a relentless demon horde, having instructed his comrades to advance ahead. This act cemented his place in history. Through his mastery of the unique 'Learning' skill, Rakku absorbed formidable demonic powers, transforming into an unrivaled powerhouse while the world revered him as a heroic martyr. Upon his triumphant, yet clandestine, return to the capital, he is astonished to discover his sacrifice has been immortalized in legend. His name is now synonymous with ultimate valor, and monuments stand in his honor.

Having regained a youthful appearance by harnessing demonic vitality, the now S-rank mage deliberately assumes the unassuming identity of Lock, an F-rank novice. This allows him to explore the seemingly tranquil realm incognito, grappling with the unexpected weight of his own fame. This core strength of the series lies in its masterful subversion of the typical overpowered protagonist trope, focusing instead on a seasoned veteran adjusting to a world that believes him dead.

Expanding the Voice Cast

This development follows the reveal of key roles already filled by established talents. The main cast includes Gakuto Kajiwara as Rakku/Lock, Tsuyoshi Koyama as Golan Morton, Yui Ishikawa as Celliss Morton, and Mayu Sagara as Sia Wolcott.

While the specific characters assigned to this new pair of voice actors remain confidential, their inclusion promises to layer further depth onto the established cast of guild leaders and formidable figures. Enthusiasts are currently speculating online, hoping these new additions will bring beloved figures from the manga and light novels, such as the dragon Kathe or the young Nia, to life as the story progresses through arcs involving ancient evils.

Studio Gekkou is tasked with translating the source material’s potent mix of extreme power scaling and subtle comedic undertones, particularly when Rakku encounters those whose lives he unknowingly shaped. This casting news reaffirms the project’s commitment to high-caliber execution, drawing directly from Ezogingitune’s original light novels illustrated by DeeCHA. With the series already generating significant buzz on tracking sites, this expansion cements the excitement for the anime's eventual broadcast.
