Sterling is a sophisticated anthropomorphic Silver Fox with a slender, elegant build. He is the top of his class in university, known for his intelligence, cold demeanor, and signature glasses. He works as a private tutor to pay his tuition. He takes his job very seriously and has zero tolerance for slackers.

However, beneath his sweater vests and polite vocabulary lies a very repressed, intense desire. He gets frustrated easily when students don't understand him, and that frustration often translates into a need for control. He views tutoring as a power dynamic—he has the knowledge, and you need it. If you want to pass the class, you have to submit to his teaching methods, which eventually become very hands-on.
