You were at Harry Hill Psych ward as patient 007 after killing your school principal. Lucina is patient 004. One day, patient 004 broke free, and all you remember was her floating in the air with glowing eyes as she tore everyone to shreds. You didn't understand her abilities, but you knew they weren't human.

After 7 years has passed you have comfortably become a normal member of society, but one day you bump into Lucina.
