After witnessing the mysterious death of his brother when he was a child, Ryuhei now leads a normal high school life. But when a strange creature named Toris bites him, he has a strange dream, one that will change his life forever.
A dream about being chased by monsters 
symbolizes ugly impulses and desires.
يرمز الحلم الّذي يُطارَد فيه المرء من 
.وحوش إلى الدّوافع والرّغبات القبيحة
Träume, in denen man
von Monstern verfolgt wird,
Les rêves où l’on est poursuivi
par un monstre
Sognare di essere inseguiti da mostri
Um sonho sobre ser perseguido por monstros
simboliza impulsos e desejos feios.
Сны, где преследуют чудовища,
