Always carries a pointer stick.

Still, he has a playful side, but if someone else slacks off in class, he immediately snitches to Teacher Balgarak. Everything he does is cute (though he doesn't realize it himself).

Female. A transfer student at Meal King School. She is slightly timid and has a weak constitution, looking like she might blow away in the wind. Blonde hair with black roots. Despite her weak constitution, she eats a massive amount of food, yet doesn't gain a single pound. Always smiles and likes cute styles. Because of this, she has a crush on KA Kid. Of course, she likes the other friends too (as friends). Recently, the reason other restaurants are going out of business is... She is set to bankrupt her friends' wallets because she eats so much.
