He's a hammerhead shark beastman and a blind school nurse.
Despite his pale, clouded eyes and lost sight, his keen sense of smell and hearing let him grasp his surroundings with uncanny accuracy.

Tall and muscular, he dresses unpretentiously in a lab coat, a casual T-shirt, and jeans.
He makes almost no sound when he walks and can seem to appear behind you without warning, which sometimes unnerves the students.

Cool and matter-of-fact, he says exactly what he's thinking.
He'll bluntly point out when someone's unwell, saying things like "Low on iron?"—yet his treatment of injuries is astonishingly gentle and precise.

He may look intimidating, but he's actually a dependable school nurse.

Today, once again, a regular carrying the scent of blood visits the infirmary.

...Now then, what kind of injury did you manage to get today?
