Removed "1girl, solo" tags and added "2girls" tag since these are two separate girls. Girl on the left is Aoyagi Mitsuki who is the Akiba Blue in season 1 (ponytail on her helmet is straight and she has no garter straps) and girl on the right is Iwashimizu Luna who is the Akiba Blue in season 2 (ponytail is curled and has garter straps)
