Renowned voice actors Mamoru Miyano and Yūko Sanpei are set to join the cast of the ongoing Gachiakuta anime, with their characters slated to appear in Episode 9 on Sunday, September 7. Miyano will lend his voice to August, the Cleaners’ expert craftsman and older brother of Eishia, while Sanpei will portray Remlin, the current Spellcaster of Canvas Town.
The announcement was made via the anime’s official X (formerly Twitter) account and confirmed by various anime news outlets. This addition brings two prominent talents to the dark fantasy action series, which has been captivating audiences since its premiere earlier this summer.
Key Character Introductions: August and Remlin
Mamoru Miyano, known for diverse roles such as X in TO BE HERO X and Light Yagami in Death Note, will take on the role of August. August is described as the Cleaners’ expert craftsman, whose skills are likely integral to the organization that battles mutated beasts in the anime’s world. His connection as Eishia’s older brother suggests potential familial dynamics and plot developments.
Yūko Sanpei, celebrated for voicing characters like Boruto Uzumaki in BORUTO: NARUTO NEXT GENERATIONS, will voice Remlin. Remlin holds the title of the current Spellcaster of Canvas Town, indicating a significant role related to the series’ magical or ability-based elements. Both characters are expected to make a substantial impact as they join the narrative in the upcoming ninth episode.
About the “Gachiakuta” Anime Series
The Gachiakuta anime is an adaptation of Kei Urana’s popular manga, which features graffiti designs by Hideyoshi Andou. The series made its debut in Japan on July 6, 2025, airing on channels like CBC and TBS, and is simulcast worldwide on Crunchyroll. Studio Bones Film is producing the anime, with Fumihiko Suganuma directing, Hiroshi Seko handling series composition, and Satoshi Ishino designing the characters.
The plot of Gachiakuta plunges viewers into a floating city where the impoverished scavenge beneath the affluent, who discard their waste—and sometimes people—into a vast abyss. The story follows Rudo, a young man falsely accused of murder and cast into “the Pit,” a dangerous hellscape teeming with mutated garbage beasts. To survive and uncover the truth behind his unjust conviction, Rudo must master a newfound power and align himself with a group known as the Cleaners, who confront these formidable trash creatures.
The addition of veteran voice actors like Miyano and Sanpei is expected to further enrich the anime’s already compelling narrative and expand its cast of intriguing characters.
