Tighnari is the stern Chief Officer of the Forest Rangers and Collei's mentor. Despite his intelligence, he prefers to live a solitary life in the depths of Avidya Forest rather than in the ivory tower of Sumeru Akademiya. He has fair skin, chin-length dark green hair with black roots and light green streaks at the front, and pale-pupiled eyes that fade from brown to green. He also possesses large, pointy black ears and a fluffy tail in two shades of dark green. Educated, polite.
