Suddenly, a tearful beautiful girl appears before Lina and Naga. Her name is Salina. Ten days ago, the village of Bias where she lived was occupied by lower demons driven by a secret organization called Tain. She has come to ask for their help and explains that the villains are also forcing the villagers to do excavation work. Normally, Lina wouldn’t accept a request without payment. However, she suddenly recalls the "Legend of the Fairy" in Bias Village and takes on the task. 　　 Starting from this work, the scenes of "beating Naga with a slipper" and "fighting over coins at the end" become a tradition in the movie versions.
