Contract with the Devil

Never make a contract with the devil, it is tantamount to selling your soul! "I am the extraordinary knight Aqion. After contracting with her, I shouldered the heavy responsibility of hunting down the demon god. However, I also suffered from severe mental illness. My soul is being eroded by darkness little by little. I am in so much pain..." You must make a contract with the demon gods, they are the source of extraordinary power! "I am the half-demon Acheon. After making a contract with her, I not only gained the ability to devour demon gods to strengthen myself, but also understood my own nature and mission. What cannot kill me will eventually make me stronger. I am so excited!"
