Opal is one of the protagonists of the Aoi Sekai no Chūshin de series. She is based off of Opa-Opa from Fantasy Zone. Opal has a dark-purple hair color and purple eyes to match. Unlike Gear and Nel, her hair color does not match the character she represents in Fantasy Zone. She has fair skin and a slender figure accented by large breasts. She has a circlet with small wings that stick out above her ears. She wears a necklace made of what looks like bells. Below, her attire leaves little to the imagination, consisting of a tan single shoulder top and loincloth, as well as a pair of black underwear and a bra, exposing a hefty amount of skin. She wears sandals that wrap around up to her calves, and carries her trademark bow and arrow at all times. Despite Gear personifying Sonic the Hedgehog, Opal is definitely more recognized as the one with the attitude. When she does not like someone, she is blunt about it. Opal has a sense of humor that is not as appreciated as she would like. Every time she makes a joke she asks "Was that funny?", in which Gear would respond with "not really...". More than her attitude, Opal is very overconfident. She has a tendency to underestimate her opponents, causing her to be easily caught off guard.
World War Blue
