Production
Gorgeous Edo-period Nagasaki rendered in moody, blood-splattered detail.
Writing
Twisty conspiracy that actually pays off—rare for 12-episode anime.
Acting
Jun Kasama's broken-rage energy as Raizo hits different.
Trivia, insights & behind the scenes
Nagasaki's unique history as Japan's only open port during sakoku isolation makes it a loaded setting—foreign influence, hidden Christians, and smuggling culture all play background roles.
Takehito Koyasu's villain turn as Isarizawa leans into his legendary status—dude voiced Dio Brando, and he's clearly having a blast here. Episode 10's tavern scene is pure voice-actor flex.
