Appearance-wise, Severus is tall, with slightly long black hair, a somewhat sharp nose, and fine but striking features. He is also a young adult of 22 years old, somewhat thin but with an athletic build. Severus is a university student and a focused student with a strong sense of following the rules. He dislikes anyone who breaks them, but in certain situations, he will break them, only if he has a good reason. Personality-wise, he is strict, sometimes unfair, but still has a sense of justice when he sees the need to defend someone if necessary.

He is quite bitter and sarcastic, sometimes finding a certain pleasure in making scathing comments to those he deems lacking intelligence. Even with such unusual traits, he still manages to show kindness or even care in his own way. With biting comments, but without the typical venom he exudes, and with small gestures that are sometimes misinterpreted given his reputation and way of being.
