Adam traveled through time and space and became a new Lord God, but because he lacked the replenishment of the origin of the world, he was on the verge of destruction. Just as he closed his eyes and waited for death, he suddenly found that countless of his selves had traveled through time and space at the same time, but they were all female versions of himself. Good news: they were all beautiful girls. Bad news: their painting style was a bit strange. Isayama Yomi: I am the only one in heaven and on earth, you are just ordinary people born in my time!

However, when he was twelve years old, Hyuga Tenkyō was unable to even refine chakra. Every time chakra was refined, it disappeared into thin air. Not to mention ninjutsu, he couldn't even use physical techniques.

After being stuck in the Genin graduation exam for three years, Hyuga Tenkyō suddenly found himself as a Jinchūriki, and the tailed beast in his body turned out to be the legendary ancestor of chakra - Kaguya Ōtsutsuki!

Let me be frank. I will stop pretending. I am Kaguya Ōtsutsuki’s Jinchūriki!
