Yamashita will voice Toshiya Kase, who is an assassin with exceptional disguise skills.
The new teaser video is also available on YouTube, but is region-locked to specific territories.
Meanwhile, the anime’s voice cast is headlined by Yusuke Kobayashi as Ikuro Hoshi and Hinano Shirahama as Sara Haizaki.
Tetsuro Amino (Onmyouji: Heian Monogatari, Lupin the Third: The Last Job, Macross 7) is directing the anime series, with Shoji Yonemura (Shaman King 2021) as series screenwriter and Shingo Fujisaki (Let This Grieving Soul Retire co-character designer) as character designer. Bridge is handling the animation production for the series.
The anime is based on the “killing hotel drama” manga series by Ao Tajima, which began serialization on Shogakukan’s Sunday Webry website on June 12, 2021 and has released 11 tankobon volumes as of June 2025.
Crunchyroll is streaming Hotel Inhumans worldwide, outside of Japan, and describes the main synopsis as:
The best hotels must meet certain standards, including the finest cuisine, ways to relax, and entertainment. Of course, they also need the best selection of weapons, reliable ways to falsify one’s identity, and ways to dispose of evidence. In this hotel at the border of death stand two concierges, Ikuro Hoshi and Sara Haizaki. What kinds of requests will the assassins have for them next?
