Project Red, from the novel Chronicles Saga that Soma read, was the project conducted by one of the seven subordinates from the Great demon lord, which involved many innocent children who were orphans, in grief, broken, and lost with no way home. The institutions enticed them using words like power, wealth, wisdom, and shelter, making them easily deceived and searched test subjects. There is also a grown-up man, which consists of a bandit or someone who has abandoned humanity itself. The project was intended to create a Demonic human.
Because the Demon Race from this world was something that was not born through race, they were created by using the devil's blood that is scattered across the globe.
As Soma recalled in the story, the project and the institute were already raided five years ago. The organization perished on the planet as they witnessed all of them being captured or killed.
