Stephanie Demillaire is a school journalist and a classmate of Doowee and Sally. She usually tries to get the latest scoop but has a tendency to rush to judgement- which has gotten her into trouble on a few occasions.
Stephanie is a determined girl who always tries to seek out information when she can; and with the desire to finally get on the front page she will do anything to try to get that perfect scoop. She is implied to be fairly vain and self-centered, and refuses to take blame for things she does.
She is easily offended and appears sensitive, but most of the time seems to be hyper and very talkative.
Stephanie is a fair-skinned girl with sky blue eyes and blonde hair worn in a high ponytail with a pink band adorned by a green ornament.
She wears a glittering red blouse with a green heart on it, big red circled earrings, a short skirt, and shoes with pink socks.
