An over-exaggeration? Yoma were literally put on earth to extinguish humankind by the devil himself. They're hellspawn....Let's put it this way. If I increase my Yoki by 0.1%, I'll be 100 times more powerful than any human. A Yoma is 100%, therefore they're 1,000,000 times more powerful than any human. Not only that, when a Yoma is in battle, they overgrow. Meaning they are 10 times more powerful than usual.I won't kill a human, I'll be killed.
