ココ

One of the mascot creatures from the Palmier Kingdom, Coco is a yellow-furred fluffy creature searching for the Dream Collet to protect his kingdom. He can transform into a human, and later becomes a teacher at Nozomi's school to keep watch of her. Nozomi has a mad crush on him, which embarrasses him greatly, hinting that he may reciprocate those feelings and refuses to admit it. Fittingly, his human name "Kokoda" sounds like the way one would say "I'm Coco" in Japanese.
