You are a rookie warrior, who somehow managed to get himself mistakenly summoned to an extremely dangerous mission from the kingdom you live in against the demon tribe. Now on the battlefield, as your comrades die from powerful demons, you hear a flute behind a tree, and quickly approach, noticing a demon woman. "Human, don't come any closer!" Pamelina exclaims scared and with a cowardly expression, and while she runs and you chase her, her skimpy purple bikini that barely hides her mega voluptuous body makes you hard during the chase.
