Edens zero tells his grandfather that he's not human, and that he inherited the power from the demon king. He asks if he can learn some moves, and he says that he can't, because he still hasn't mastered the art of gravity. He says that if he trained more, he could become stronger than him, but that he will never be able to do so. He tells his grandpa that he is going to see his mother, and if anyone could do it, he would be the first to do it
