Tighnari uses the medium male model. 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. He serves as a mentor to Collei, who in turn sees him as a Master of some sorts and holds him with high regard. While he is friends with Cyno, he does not appreciate his jokes.
