Reincarnated Devil’s Plan For Raising The Strongest Hero

After being defeated in the demon world, a powerful demon lord is reincarnated as a human child. Instead of seeking revenge, he decides to raise the next generation’s greatest hero himself. Using his past-life knowledge, ruthless training methods, and twisted sense of love, he molds a weak boy into an unstoppable warrior. But as emotions and bonds grow, the demon begins to question whether creating the strongest hero will save the world or destroy it.
