A fan-created costume by GreyEth.
While visually similar to Atago's Stunning Speedster costume, it is differentiated by a cropped sweater in place of the cropped suit jacket, the Japanese flag on the darker shoulder portions of the jacket (along with the name and initial of "A.Tago"), the logos of various space agencies (namely JAXA, though NASA and SpaceX also make appearances) on the sweater, as well as various "Remove Before Flight" pull-tabs on both the bikini top and bikini bottom. The design of the bikini is also different: the logos of the space agencies sometimes appears on the bra of the bikini top, and the bikini bottom has been changed into a side-tie bikini.
