Emily Orange is an American foreign exchange student at the Japan branch of California Coast High School. As the Shooter for the Unkai Surfers team, she partners with Jennifer Peach, the Jetter pilot. She possesses blonde hair, cyan eyes, tanned skin, and stands 170 cm tall. Her typical attire reflects gyaru fashion: a midriff-baring top, skirt, headband, choker, bracelets, and flip-flops.

Emily exhibits a strong fascination with Japanese culture, particularly ninjas, idols, and anime. This enthusiasm influences her speech, where she incorporates the archaic Japanese suffix "-gozaru". She actively participates in cultural activities, like impromptu plays during promotional shoots and beach outings, once cuddling Rin Namiki alongside Jennifer Peach.

Her role involves using a water bazooka during Jet Races to trigger opponents' purge safety mechanisms. While dedicated, Emily prioritizes enjoyment over intense competition. She displays a friendly and physically affectionate demeanor, feeding Yuzu Midorikawa a piece of canned orange and initiating hugs. Her camaraderie with Jennifer Peach includes a shared appreciation for Japanese history—Emily favoring ninjas and Jennifer admiring samurai.

In the series' OVA, Emily participated in creating promotional content for Jet Racing, contributing to a lighthearted segment featuring improvised acting. Her relationships maintain friendly rivalries with other teams, consistently prioritizing fun within the sport.
