The demon government dispatched demon world investigators to the human world to track down the evil youkai who escaped from the demon world. Her name is Pai Nyan Nyan! Having a youkai white daughter as her mother, she uses her special skill, Snake Dragon White Scale Fist, to knock down youkai like a locust. Please enjoy the parody gag and slightly sexy Chinese-style dish. In addition, this work was published irregularly in Magazine Z (Kodansha), but only the last episode 6 was unpublished, so this is the first public release.
