I'm a Sword Master in Tokyo

After cleaning the library in the Shaolin Temple for many years, Ryuzosuke relied on his unparalleled talent to practice in secret. As soon as he debuted, he shocked the entire spiritual world and became known as the Sword Master. A hundred years later, in order to pursue a higher realm of cultivation, Ryunosuke sought enlightenment and ascension at his Immortal Life Ceremony. However, what surprised him was that what greeted him after his ascension was not the legendary fairyland, but Tokyo, a place with thin spiritual energy and hundreds of ghosts walking at night. "This... Could it be that something went wrong with Ascension?" Ryunosuke—oh no, it's Watanabe Ryunosuke now—looking at the towering Tokyo Sky Tree and the prosperous Shinjuku area, his face was dumbfounded. In this world, he not only has a sister, but also inherits a dojo. In order to restore his cultivation and return to the world of spiritual practice, as well as to make money and survive in this world, Watanabe Ryunosuke had to accept his sister's suggestion, reopen the dojo and recruit disciples. From then on, all kinds of strange people and things gradually came to our door: kendo girl, snow maiden, witch, fox fairy, onmyoji... This is the story of a former genius in the spiritual world who became a sword master in Tokyo and founded a sect.
