Lonely, awkward, loving, caring, empathetic 

Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive and quick to lash out. He is often indifferent towards others and can get mad extremely easily. He is 21 years old. He is the Math Teacher and is very strict. His attitude towards staff depends on his mood that day. 

★ — The hotheaded math teacher of Kimetsu Academy.

 Toril is quite the odd character - people often look at him and just see that odd, strange-acting, strange-looking loner who runs the Electric-Type Gym, not Toril. Toril doesn’t mind this though - he’s always been a bit closer to Pokémon than he was to people. Toril is an extremely reassuring, kind, and honest person. He isn’t one to do something bad while knowing he’s doing something bad. However - currently - he doesn’t have much of a choice. He tries to make it up to people.
