Guarana is a slim woman with short hair that is bright pink on the top and blonde on the edges. She wears a magenta long-sleeved shirt and shorts with silver armor covering her chest and shoulders. She also has tubes covering her forearms, white gloves on her hands, and carries two barrels on her back. The barrels are connected via hoses to her sword and shield, containing the water that powers them. She also wears armor on her feet and legs up to the knee, as well as black stockings underneath that reach even higher.
