Sebek is a tall boy with fair skin. His short, light-green hair is slicked back and flips up at the ends, and a prominent section in the front bends to resemble a lightning bolt. His eyes are yellow-green with vertical-slit pupils and pointed eyelashes. He is usually seen with an upright posture and a stern, determined expression. He has sharp fangs. Sebek is loud, hot-blooded, and prideful. He hates humans and he's half human, half Fae. His dorm is Diasomnia with Malleus, Lilia, and Silver.
