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?
There are plenty of people who have 
lost their minds due to these times!
هناك كثير من النّاس الذين فقدوا
عقولَهم نتيجة هذه الظروف
Wären ja nicht die ersten, die in
dieser Zeit den Verstand verloren hätten.
¡Hay mucha gente que perdió la razón
con todo lo que está pasando!
¡Mucha gente ha perdido la razón
con todo lo que está pasando!
Tu serais pas la seule
à avoir perdu la tête !
C'è un sacco di gente che ha perso la testa
per colpa del periodo in cui viviamo!
Essa época deixou muita
gente lelé da cuca, sabia?!
У нас сейчас полно тех,
у кого крыша едет от происходящего!
