As announced on the official Good Smile Gumako Twitter, Gumako is to join Mirai Suenaga and friends a Mirai Millennium character ^o^
To celebrate, get this high res wallpaper at Flickr - look for the "original size" link on the right.
Our first collaboration will be a figma where Gumako will be wearing Mirai's Summer School Uniform. Pre-order info up soon!
Will soon get Iizuki Tasuku-sensei doodle up Gumako to fit in with the rest of the team. In the meanwhile this wallpaper at Flickr.
