It is not human nature to live only safely under the protection of someone powerful. Humans are different from beasts because they have a spirit of challenge, a spirit of adventure, and a free will not to be tamed. Angels and demons... Weak humanity has suffered from time immemorial due to the vicarious war of beings who can never resist. Humans in a cluster organized to escape from the pain that has been stuck like a custom set out to find a third being... The unknown being touched by many sacrifices and trial and error can rule out the interference of angels and demons. Gives you the strength that you have. To break away from good and evil, the damn dichotomy, and pioneer a new path! A new concept of exorcism action where characters with third power fight against countless demons and angels!
