There are people under there. Fans of the anime Love Live. They’re called “Love Livers” (ラブライバー or rabu raibaa) for good reason, because they really, really adore Love Live.
Previously, Kotaku introduced the fans’ hardcore outfits, made up of buttons, plush toys, and straps. In comparison to this latest evolution (photos by vicks2054), those get-ups are rather tame!
Dont know f this counts as cosplay or not but I added it anyway. You wouldn't want to stand downwind near any of these people. You aren't going to smell like roses lugging around 50lbs of Anime Merch all over your body =p
