Holding a Zanpakutō and Leading the Ninja World Towards the Grand Route

Xu Kaixi, a 'lucky man' who died of overwork. I thought I had traveled to the world of Naruto. And it was still the Kirigakure Village during the Blood Mist Policy. Fortunately, he was rescued by Terumi Mei when he was a girl and became his teacher. A few years later, he discovered that the world was anything but simple. What are those black-robed warriors invisible to ordinary people? And those monsters with masks on their faces and holes in their chests! Are those talking animals in the three holy places really 'immortals'? Where did the Ganshi clan come from? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
