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?
We've already been transported to a place 
that might as well be the afterlife,
،نُقِلنا بالفعل إلى مكانٍ قد يكون الحياة الآخرة
Wir sind an einem Ort gelandet,
der ebenso gut die Hölle sein könnte.
Venimos a un sitio
que parece el más allá
Hemos llegado a un sitio
que parece el otro mundo
Alors non seulement on est transportés
dans ce monde étrange,
Siamo stati trasportati in un posto
che potrebbe anche essere l'aldilà,
A gente já foi transportado pra um
lugar que parece ser de outro mundo,
Мало того, что попали в место, которое
можно назвать загробным миром,
