Original male protagonist (Shifengyuan Idle) x Osamu Dazai
Two-way redemption
He is a descendant of the Sifengyuan family. The Sifengyuan family has the power that is envied by countless people: Thousands of years ago, the patriarch of the Sifengyuan family signed an agreement with the devil. The descendants of the Sifengyuan family will have the power that others envy, but there is also a price: losing a piece of human essence. What he lost was the essence that makes people crazy: pain. He had self-mutilated, and no matter how severe the injury, he felt no pain, only an amplified feeling of weakness and dizziness.
There is no such thing as a miracle in this world, and even if it were, it would not happen to someone like me who is working with the devil - Sifengyuan Idle
Did you know? I once sat alone in the rainy night, expecting a miracle to come, but the miracle abandoned me in the end - Sifengyuan Waiting
Instead of expecting these vain things, why not give it a try yourself? You are just looking for excuses for your laziness - Sifengyuan Waiting
Did you see it? This is the ugliness of human nature, lying on the ground like a dog, begging for forgiveness, but why should I forgive you? How ridiculous, because I am the devil's executioner, because I originally wanted to crush your ridiculous vanity - Sifengyuan Idle
He was abandoned by this world
This is his answer:
I am a member of the Sifengyuan family, a person who associates with the devil, and the most loyal executioner.
Intention: Two-way redemption
