mass update favgroup:55098 -> tenga_suit
Was a little surprised that this tag wasn't there. There is a corresponding tag TENGAスーツ on Pixiv.
There is a copyright tag Tengirl used for Tenga's official anthropomorphic characters though, but the design may differ from those so not very suitable for cosplay tag.
