Cocytus

Cocytus 「コキュートス, Kokyūtosu」is an extremely powerful spirit both summoned and named by Runaos Genesis.

Appearance
Cocytus is a tall, well-built spirit. His eyes are black and so is his hair, which is kept short and styled into a number of spiky strands pointing backward with some prominent spikes topping his forehead; his thin sideburns reach down to the stubble covering the majority of his chin. He has a sharp face, marked facial features, and slight wrinkles below his eyes, as well as a long scar extending from his hairline to his lower left ear. Both of his ears are adorned by silver-colored earrings, consisting of a ring with a little chain ending in a cross pendant.
