Lefiya Viridis

A 15-year-old elf girl with amber-colored hair. She ranks up to Lv.4 before the final battle of Knossos. In the main story, it is difficult to delve into Ais's settings, so she was created as a character in the side story to explore various aspects and is one of the protagonists of the side story. With the start of a new chapter in the side story, her appearance and personality are revamped from volume 13 of the side story.

She hails from the forest of Wishe, known for its exceptional magic, and joins the Loki Familia from the "Academy District." She has a kind-hearted personality and particularly admires Ais. She also harbors a one-sided rivalry with Bell, showing anxiety upon learning of his rank-up. Although she feels jealousy and hostility towards Bell, she understands his character through their cooperation on the 18th floor and ends up cheering for him during his battle with Asterios, becoming one of those inspired by Bell's adventures. She also deepens her personal friendship with Filvis of the Dionysus Familia, with whom they form an alliance, but struggles with sadness and conflict upon learning Filvis's true identity and ultimately defeats her.

In combat, she is a magic-specialized rear guard capable of casting magic that surpasses the attack power of Ais and the Hiryute sisters, earning her the nickname "Foolish Magic Power" from Loki. She possesses a summoning magic that allows her to use other people's magic if she fully understands the chant and its effects, which is the origin of her alias. This summoning magic enables her to use all of Riveria's magic, and she receives daily guidance from Riveria as her potential successor when Riveria eventually leaves the Familia. Upon ranking up to Lv.4, she manifests a rare skill that allows her to hold a pre-chant magic while casting another, and activate the held magic at will without abandoning the ongoing chant.

Her alias is "Thousand Elf."
