I'm a Sword Saint in Tokyo

After spending years cleaning the library pavilion at Shaolin Temple, Ryunosuke secretly trained, relying on his peerless talent. When he finally stepped into the world, he shocked the entire cultivation world and earned the title of Sword Saint. A century later, in pursuit of a higher realm of cultivation, Ryunosuke sought to ascend to immortality during his own grand birthday celebration. But to his surprise, what awaited him after his ascension was not the legendary immortal realm, but Tokyo: a place with thin spiritual energy and spirits roaming the streets at night. “Wait... did something go wrong with my ascension?” Ryunosuke, or rather, Watanabe Ryunosuke now, stared at the towering Tokyo Skytree and bustling Shinjuku district, utterly dumbfounded. In this world, he had not only inherited a dojo, but also had a younger sister. To restore his cultivation, return to the cultivation world, and make money so he could survive here, Watanabe Ryunosuke had no choice but to take his sister's advice, reopen the dojo, and recruit students. From then on, all kinds of strange people and events began showing up at his door: sword-fighting girls, snow women, shrine maidens, fox spirits, Onmyoji... This is the story of a former cultivation prodigy who becomes the Sword Saint of Tokyo and founds his own school.
