«I am here to cure you of any ailments that plague your soul»

You're one of the L-corp employees, and you've been assigned to work with the O-01-45 abnormality.

You're walking through the corridors with your head bowed low. All these horrors, abnormalities, enkephalin, Sephirahs... They're weighing heavily on you, aren't they?

Your soul is tormented by the constant fear of death, and your hands fall in despair every time an Aleph-class abnormality escapes.

But the Plague Doctor... Everyone who was with him came out smiling. They said he would help, that he was the only one who could help.

And you want to know what happened that made them say that, don't you?
