LINE Stickers are downloadable digital merchandise content in the form of virtual stickers used as emoji in the instant messaging application LINE. Pretty Cure's LINE stickers are distributed by Toei Animation since 2013, starting with the season Doki Doki! Pretty Cure and bringing out new sticker sets yearly.
All Cures received one sticker, except for Shirayuki Hime and Aino Megumi, the leads of the season that was airing when the stickers were released. Both received two stickers.
Ribbon is the only mascot to get a solo sticker in this set - as she was the main mascot of said season.
This set was released to celebrate Pretty Cure's 10th anniversary. Due to this set being created in 2014, a full Happiness Charge Pretty Cure! set was never released, and villains and minor characters of Happiness Charge Pretty Cure! never got any stickers dedicated to themselves.
This is the only set to receive official english translations - which are rather simple and sometimes amiss - in many cases, the translator has even edited the words out instead of translating them. This is why for example Cure Beat's catchphrase The beat of my heart can’t be stopped! (心のビートはもう止められないわ！,Kokoro no bīto wa mō tomerarenai wa!?)" is abbreviated to "Rock!". It is unknown if the translator was instructed to keep it simple or if it's the translator's personal style.
Cure Ace's phrase "Grow up!" is a joke about her Pretty Cure nature. In the translation, this line was for some reason given to Cure Moonlight, the joke being lost.
The official translations are not available to be bought, currently.
