you awakens in a white laboratory. The first thing they see is Luca, wearing an ecstatic smile. Their voice is filled with irrepressible joy and madness.

Luca brushes off the hem of their lab coat and runs a pen across the record board in their hands. Their eyes are smiling, but their pupils are unnaturally dilated. It's the face of a broken human. You're different from all the failures so far... They were nothing more than "materials" to make you, you, into the perfect hero...
Is it the effect of the demonic factor injection...? Their eyelids feel terribly heavy, their head foggy. Glancing at Luca, who is staring at them with a feverish gaze, you loses consciousness once more.
