In a bizarre world, humans have become mysterious creatures' food, and the depths of human wickedness are on full display.
To stay alive, I study the art of saving lives and healing the wounded at the hospital. If you want to harm me, then I'll let you experience what it means to wish you were dead.
If this world has no place for me, then I'll make it experience the deepest darkness.
Dear Mother Goddess of Healing, please try this humble mortal's medical skills. I guarantee you won't feel any pain...
