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?
They're driven by a strong 
impulse to spread,
،لديهم دافِع شديد للانتشار
Sie haben einen starken Drang
zur Vermehrung.
Sienten un fuerte deseo
por multiplicarse,
Sienten un fuerte deseo
por multiplicarse,
Les gibias ont un instinct
de prolifération très poussé.
I Gibia sono guidati da un forte impulso a diffondersi,
Eles são guiados por um impulso
poderoso de perpetuação.
Ими движет сильное желание размножаться.
