As the article title says, another set of Charlotte stickers have been published for the popular smartphone messaging app, LINE. These stickers, unlike the previous set, are based off of the Charlotte 4-koma, and are illustrated by the same artist, Komowata. Also unlike the previous set, these stickers are published not under Aniplex, but under Key (much like the ABOW and CLANNAD stickers). This of course means that you should be able to purchase these stickers anywhere in the world! Thanks, Key.
