Mitsuki Saiga has joined the voice cast of Hotel Inhumans Season 2 to play the character Sekiya. The announcement, shared via the series' official website and reported by Anime News Network on October 29, 2026, adds a veteran presence to the ongoing Fall 2026 production.
The second season of the noir-inspired series premiered on October 4, 2026, and is currently airing its 13-episode run. Saiga's character is introduced as a guest at the titular hotel, a luxury establishment that exclusively provides specialized services for professional assassins, ranging from forged identities to body disposal.
What We Know
According to Crunchyroll News, Mitsuki Saiga is cast as Sekiya, a guest whose arrival contributes to the show's dark, atmospheric tone. Saiga is well-known in the industry for her work in androgynous or authoritative roles, which aligns with the "mysterious" description of the character provided by the production.
The series is produced by studios Bridge and Aisle, with Aisle serving as a subsidiary of Bridge established in May 2025. Tetsuro Amino is directing the season, while Shoji Yonemura handles series composition. Saiga joins a cast that includes returning leads Yusuke Kobayashi as Ikuro Hoshi and Hinano Shirahama as Sara Haizaki. Other new additions for the second season include Hina Yomiya as Shiba Kirihara and Shoya Chiba as Subaru Yoda.
The production features a musical score by Koharu of Charan-Po-Rantan and sound direction by Haru Yamada. The opening theme song is "Rasen" (Spiral) by GAN, performed by Takanori Iwata, while the ending theme is "Sweet Pea" by Phantom Siita. Character designs for the series are provided by Shingo Fujisaki.
Why It Matters
Hotel Inhumans is based on the manga by Ao Tajima, which was serialized in Shogakukan's Sunday Webry and concluded with its 12th volume in September 2025. The story focuses on the logistical side of the underworld, where concierges manage everything from gourmet catering to forensic cleanup for their lethal clientele. The addition of guest characters like Sekiya allows the series to explore standalone vignettes within the broader narrative of the hotel's operations, maintaining the noir aesthetic that defined the first season.

Hotel Inhumans Season 2 is streaming on Crunchyroll in North America, Central America, South America, Europe, Africa, Oceania, the Middle East, CIS, the Indian Subcontinent, and Southeast Asia. For viewers in Southeast Asia, the series is also available via Medialink/Ani-One Asia. An English dub is currently in production and available on Crunchyroll as of October 2026, though regional availability for the dubbed version may vary.
What Happens Next
