Lily is a high pixie, a rare fairy species that inhabits forests and forest dungeons within the world of the series. She is small in stature and possesses a mischievous streak, often using her tiny body to play pranks on others, particularly on Tama and Aria. Her playful nature makes her a source of lighthearted entertainment among the group. Lily is best friends with Feri, and the two share a fondness for sweet treats. Despite her innocent appearance, she is a capable combatant; her primary attack skill is called Fairy Bullet, which allows her to fire beams of light at tremendous speed, piercing through enemies. In the story, she serves as a supporting character who interacts regularly with the main cast, adding a playful dynamic to the group's adventures. Her motivations are not deeply explored, but she appears to enjoy her life in the forest and the company of her friends, with no notable character development over the course of the series.
