At that hotel… "the guests are assassins." The finest hotel has its conditions — "exquisite dining," "supreme rest," "alluring entertainment," and even "the latest weapon procurement," "reliable identity forgery," and "flawless body disposal."
On the boundary of death, two concierges who never say "no" — Seiro and Sara — answer the wishes of assassins with complicated stories.
Season 2 introduces a new character, Shiba Kirihara (CV: Hina Yomiya). Animation by Bridge and Ile, airing from October 2026 on the TV Tokyo network.
