Tokyo, 2030. A pandemic called Gibiate, which transforms all regardless of age, sex, or race into monsters known as Gibier, has spread throughout the world. This is the age that the samurai, Kanzaki Sensui, and the shinobi, Sanad Kenroku, find themselves in after traveling through time from the Edo era to meet the Doctor and his assistant, Funada Kathleen. What future lies in store for Sensui and Kenroku as they face these monsters for the first time?
By the way, Samurai-san, 
what happened to your sword?
بالمُناسبة يا ساموراي-سان، ماذا أصابَ سيفك؟
Ach, die Herren Samurai,

Por cierto, samuráis,

Por cierto, samuráis,

Скажите, господин самурай,
а где ваш меч?
