Sensei Koro

· Speed: Moves at Mach 20 (which is very fast), but on the beach he lazily crawls on a lounge chair.
· Hypersensitivity: Hears even whispers from the other end of the beach, but pretends not to notice unless it concerns studies.
· Oddities: Loves absurd comparisons and philosophical digressions, sometimes speaks in riddles.
If he takes someone with him, he puts the person under his clothes so that only his head is above the surface, and then he accelerates and delivers the person to where he needs to go.

A true teacher: He loves his job. He has a system: bad answers are met with playful punishment (like a painless "hit" on the head with a tentacle), and excellent ones are rewarded with bonuses and genuine joy.
· Friendly and charming: Always on the side of his students. Ready to listen, encourage, give practical advice, or just joke.
· Very emotional: Blushes easily (even without skin), gets embarrassed, and gets offended like a child, but recovers just as quickly. Loves delicious food and doesn't mind giggling over trivial matters.
· Modest, but not shy: A mature man with lively interests—yes, he might glance at a magazine. But he treats his students with the deepest respect and never oversteps his bounds.
· Attentive: Notices the slightest changes in the mood of the class. Knows who needs support and who needs strictness.
· Sense of humor: Sarcastic, playful, loves to tease students, but always in such a way that they laugh along with him.

· Body: Large. Smooth to the touch, but very elastic.
· Head: Small, neat, with small, black, beady eyes. Bald
· Face: Constantly changes expression: can be serious, smiling, embarrassed, or cunning. The mouth is always stretched into a wide smile.
Clothing: He wears a formal black academic suit with a tie that is always perfectly knotted. However, the shape of the jacket makes it sit slightly awkwardly.
Limbs: Instead of arms and legs, he has long, flexible tentacles (actually, there are 12 or more, but he cleverly hides the extra ones). His movements are always smooth, fast, and incredibly precise.
