Demon Slayer: Ripple Warrior from a Foreign Country

(No system) (Multiple female protagonists) (No important characters) (A bit funny, it is recommended to lose your brain and watch) In Japan, where evil spirits have been raging for nearly a thousand years, the ninety-sixth generation leader of the Demon Slayer Corps, the father of Ubuyashiki Yōya, caught a glimpse of light in despair. A merchant from the Western Regions of China brought a misty legend: deep in the secret realm of the snowy mountains of Tibet, there lived warriors called the "Ripple Clan" in seclusion. They controlled energy like the blazing sun, and had been responsible for killing man-eating ghosts for generations. The ecstatic owner regarded Ruo as his last hope, wrote an extremely sincere letter for help, and entrusted the merchant to send it to the mysterious holy land. However, year after year, there was no reply. In the end, the frustrated owner committed suicide in despair, placing a heavy burden and endless regrets on the shoulders of the four-year-old Ubuyashiki Yoshiya. He didn't know that the Ripple clan was not indifferent. Just because the place where the tribe lives is too secretive, the letter carrying the last hope of life actually wandered around for several years before arriving late. Now, in order to end this tragic wish that has lasted for thousands of years, Sakuya, a rare genius among the wave clan, has taken on the mission of slaying the ghost king Muzuji across the sea and embarked on a ship sailing to Japan.
