Only the chosen warriors known as Vessels of Heroic Blood possess the ability to turn their own blood into weapons known as blood armaments.
First Chihiro, then his friend Kotetsu awaken as Vessels of Heroic Blood. And who are these people who keep transforming innocent people into monsters?!
The Vessels who awakened one after another throughout the course of a fierce battle are taken to Maldeus Church.
Once they arrive, the mysteriuos girl Dux has something to tell them...
Not even we know what happens 
to those we switch places with.
ولا حتّى نحن نعرف ماذا يحلّ بأولئك
الذين نحلُّ مكانهم
Nicht einmal wir wissen, was mit
denen geschieht, die mit uns tauschen.
Ni siquiera nosotras sabemos
qué pasa con ellas al tomar su lugar.
Ni siquiera nosotras sabemos
qué pasa con ellas al tomar su lugar.
Non sappiamo neanche noi che fine facciano
le persone con cui ci scambiamo.
Nem nós sabemos o que acontece com
aqueles que trocam de lugar com a gente.
Даже мы не знаем, что случается
с теми, в чьи тела мы вселяемся.
