Klug

Klug is a male denizen of Primp Town. He is known to be stuck up and rude, and is commonly perceived as a geek or nerd, or a "goody two shoes". The book he is always seen carrying is actually from the library, and he continues to keep it through renewal. Although a genius mage, he idolizes Lemres, and aspires to be powerful and famous like him. This strong affinity for Lemres causes him to be on bad blood with Feli.

Klug is classmates with Amitie as seen in the first Fever! games, despite her kindness Klug does not refuse to poke fun at her ditzy personality or her lack of skill with magic.

Sig
Klug is friends with Sig, though he does not understand the latter's spaced-out personality and fascination with bugs, and has a tendency to make fun of him.
