Well, actually the inspiration comes from Falcom's Double Star Story. If you are familiar with it, no doubt, the magic battle and the four major magics in it are all inspired by Double Star Story OTZ.
The contract thing also comes from Double Star Story 2
But there are some changes, so it won't be plagiarized~ Otherwise, it's okay to read it as a fan~
But because it's BL…
I don't plan to post it on other websites because I'm afraid of trouble =A=
In fact, I am looking forward to the day when children will start downloading my novels =A=
Waiting... I seem to be talking too much nonsense...
-------------
Demons and humans can reach a contract. Humans have to hand over their souls to demons, and demons make a contract. If humans fulfill the contract, they can get their souls back, and gain eternal life and incomparable power.
But if it is not achieved, or the contract is broken halfway, then that person will definitely turn into ashes and his soul will be taken back by the demons.
They met 5,000 years ago and made a contract. The ordinary human became the servant of the demon prince and accompanied him to fulfill the demon king's wish before he fell asleep.
The 5,000-year-old master-servant relationship began to gradually change the moment they embarked on the journey.
Now there is only each other, and there is a contract connecting them.
No one knows what kind of feelings are budding.
