A young woman from the Oxagon homeworld of Deep Plains, where the Orange clan has lived happily for thousands of years. She came to the resort city planet of Spring to escape from a loud and chaotic family life. Mercury keeps an eye on her in case her naive nature gets her in trouble in the city.

Summer has remarkably few reptilian features compared to the rest of her family, but her sharp teeth and powerful body heat are unmistakable features of the "dragon" side of an oxagon.
