"Humans are the real monsters. Some of these humans are nice people, and some of them are more monstrous that the demons and unknown beings they fear. Some humans just want to win in a cruel lifestyle. And some of these humans, just want to bathe in the blood of innocents for fun. This type of monsters....I'll eradicate!
