Kazekaze thought he was just an ordinary kid in the world of Naruto.- No Sharingan.- No Byakugan.- No Ōtsutsuki bloodline.Just a normal seven-year-old trying to survive in a ninja-filled world.That was… until his father brought him back to Konoha.And he discovered the terrifying truth:* Senju Hashirama, the God of Shinobi, is his grandfather!* Senju Tobirama, the Creator of Ninjutsu, is his great-uncle!With the blood of legends flowing through his veins, Kazekaze must rise to become a shinobi worthy of his lineage.A Genius Among Monsters—But Can He Surpass Them?

Thousands of years ago, a small planet collided with Earth and destroyed the world. In five days, ninety percent of humans had been wiped out, leaving behind the last ten percent to earnestly struggle on death’s door.

Jinyu was one of those people who survived. Due to a special heredity trait, he could understand beast language. After the apocalyptic disasters, Jinyu had been living for a month with the few small beast brothers that he’d subdued. Previously, Jinyu had thought that he would live like that until he died. Yet, inexplicably, one day he opened his eyes to find that he was in a monstrous, lawless world that was full of vitality and life.

Jinyu’s transmigration into the future let him skip over almost one hundred thousand years. In the year 106825, beasts rule the galaxies and ‘pure’ humans are extinct. As the one and only ‘pure’ human left in the entire universe, Jinyu braves this new chaotic world to find a place for himself and thus begins to work at Beast Store number 138.
