Bios Ex: Yami no Wakusei

Sapporo 1997

When Eiza wakes up on the cold floor of a jail cell, his mind is completely blank. He remembers only two things: his name and that he’s not a terrorist. However, the government seems to think the opposite; they accuse him of a bombing attack to the local University in his hometown. Journalists, media, police officers…everyone blames it on him.

It’s a death sentence. But only if the Ori Asylum will declare he wasn't mentally stable at the moment of the attack, there will be a chance to save him from the grim reaper. To determine his psychological conditions, he was sent to the psychiatric hospital of Sapporo; there, he finds himself trapped in an unsettling, suffocating reality that makes him doubt the truth of everything he’s been told until that moment. Between mixed memories and unexplainable events, he meets three girls who’ll change his life: Innocent Shizune and her mysterious sketchbook, the alluring vice-director Nao and Supra with her sad eyes.

If Eiza wants to break free from his cage, he has no other choice than investigate and discover the truth about who he is and what he has done.
