朝の来ない夜に抱かれて -ETERNAL NIGHT-

Tatsuto gets along well with his childhood friend, Misora. Days pass happily until a monster appears from the "gate of the other world" and kills Tatsuto, who then makes a contract with an evil god to be revived. The monster is quickly slain by the revived Tatsuto, but this is only the beginning of the battle that approaches.
