A case of insomnia swept across the globe. As a side effect of the drug developed to suppress this sickness of causes unknown, the “bloodivores” were born. Born from bloodivore and human parents, protagonist Mi Ryu was known as “The Child of Hope” tying bloodivore and humankind together. However, when Miryu is arrested as the principal offender in a bank robbery, he is taken to a special prison operated by the Bureau of Special Threat Management for observing bloodivores.
Waiting for him there was a 
survival game of life and death.
 ما كان بانتظاره هناك هي لعبة بقاء بين الحياة والموت
Und dort wartete auf ihn …
Ahí lo espera
un letal juego de supervivencia.
Ahí lo espera
un letal juego de supervivencia.
L’objectif de ce camp,
vivre ou mourir.
Lì lo aspetta un terribile gioco
per la sopravvivenza,
fra la vita e la morte.
Esperando por ele estava 
um jogo de sobrevivência.
