Hailing from Strawberry Fields, a kingdom solely of women, Luna witnesses her village thrown into crisis. Monstrous Dragon Knights, commanded by the demon Gazelbaan, invade the sacred Goddess' Tower. They corrupt the land, petrify the goddess Aquarina, and imprison the warrior women, including Luna's mother. Seeking outside help, Luna encounters the swordsman Takeru after he enters her deserted town and is detained for theft. Recognizing him as the prophesied savior destined to rescue her homeland, Luna pleads for his aid against Gazelbaan's forces, initiating his involvement.

Luna possesses red hair, wears a distinctive headband, and has a notable snaggletooth. She accompanies Takeru on the perilous mission to the demon-occupied castle, aiming to recover six magical gems vital to the goddess's power and liberate the captive women. Throughout the journey, Luna demonstrates courage and resolve, confronting dangers within the castle walls. At a critical moment, she sacrifices herself, interposing her body to shield Takeru from a lethal attack and perishing.

Luna's legacy extends beyond her death through her lineage. Romantically linked with Takeru, she gives birth to their son, Kakeru. Kakeru later becomes the protagonist facing new threats, including the wizard Lushifon, inheriting his parents' intertwined destinies. Luna's own background as a sorceress contributes to her son's inherited magical capabilities.
