Vampires. That is the true form of Hideyoshi. Shinga is a world where non-human tribes of vampires and werewolves live. By chance it is discovered that Yuzuki blood has the ability to awaken the latent powers of Gegga Tribe members, much like the mysterious Himemiko who has vanished. While the ability of her blood makes Yuzuki valuable in a battle, it also has the potential to become a reason why she might become a target. Hideyoshi tells Yuzuki that he will protect her, but she has to marry him first.
I woke up and found myself
lying here in this world,
وجدت نفسي مستلقيةً
،في هذا العالم فجأة
Als ich aufwachte,
fand ich mich in dieser Welt wieder
Me desperté y estaba en este mundo,
Me desperté y estaba en este mundo,
Je me suis réveillée
dans votre monde…
Quando ho ripreso i sensi, 
mi sono ritrovata in questo mondo.
Quando acordei, me dei conta
de que estava caída neste mundo.
Когда я очнулась,
то была уже в этом мире,
