The retro future outfit was first worn in February 2002.
Makky's is orange, Mayu-chan's is red, and Miyuu's is blue.
Makky and Mayu-chan's outfits had skirts, but Miyuu's outfit had pants.
Originally it was long pants, but later it got changed to short shorts. (^_^;
Miyuu plays the role of the "prince" for this outfit.
When Momose joined the group, she was given a yellow outfit (with a skirt).
