Lumina

SPOILERS BELOW IF YOU HAVEN'T READ THE WEB OR LIGHT NOVELS!

Lumina is a dungeon master and the first evolved Beastman of the Black Cat Tribe that Fran meets, a Black Tiger.

Background
Prior to becoming an adventurer and then a Dungeon Master, Lumina was once an advisor to the Royal Family of Beastmen that ruled before the current family. Unable to convince the Black Cat Royal Family to cease their plans to unseal the Evil God, she incurred their displeasure and was removed from her post as a royal advisor. From that point on, she became an adventurer and eventually became a dungeon master, living for over 500 years since the Black Cats were cursed by the Gods for the sins of the Black Cat Tribe Royal Family of the Beastmen.

Lumina was prevented by the Gods from revealing how to evolve. She did offer to help Kiara evolve by turning herself into an evil being and allowing Kiara to kill her. Kiara refused to evolve at the cost of her friend's life and left Ulmet, searching for a way to evolve.

Later she met Fran who was guided to her by Dias and Aurel. She asked Fran if she was willing to kill her in order to obtain evolution. Fran refused. Lumina and Fran became friends. Lumina, who spent the past 50 years saving up magic power, summoned an A ranked Evil Being and told Fran to defeat it and absorb its magic stone. (Web Novel Volume 5 Chapter 204).. This left Lumina weakened and Fran, after defeating the Evil Being, a Black Heavenly Tigerkin.
