>>4254590Its from the Magia Record mobile game, though those costumes haven't been released yet its likely that Kyouko will show up in the second half of the current event wearing them at some point and then there will be a flurry of new fanart of her wearing them.
She also showed up in Devil Homura's side story wearing the Mitakihara School Uniform which she's not been shown in the game wearing yet.
