Human, monsters, and beasts... The world doesn't forgive them... There is a town where mysterious cases often happen. The ones who have special ability called Enja. The origin of Enja is "devil". They get together as if led by something unseen and kill each other. Sora is an Enja boy. He lost his parents several years ago and now lives alone. His life is full of peace, rest, and destruction. Peaceful school life with friends. Strange dreams he has every day. Battles against devils that appear in the town at night. His "contract" leads him to a hell of sadness, fights, and carnage. He also meets some girls along the way. Love, obedience, subordination, immorality, and desire. Sora, who doesn't know how to love, is a broken human. What does Sora get, what does Sora lose through contracts with the girls? At the end of the contract, he meets the last devil...
