Sailor Moon Crystal is a 2014 original net animation adaptation of the shōjo manga series Sailor Moon written and illustrated by Naoko Takeuchi and produced in commemoration of the original series' 20th anniversary. The series was streamed worldwide on Niconico from July 5, 2014 to July 18, 2015. New episodes were released twice a month.

 

Instead of remaking the 1992–97 anime series preceding it, Toei produced Crystal as a reboot of Sailor Moon and as a more faithful adaptation of the manga by omitting much of the original material from the first series. The story focuses on Usagi Tsukino, who is a young girl that obtains the power to become the titular character. Other Sailor Guardians join her in search for Princess Serenity and the Silver Crystal.

​

So far Sailor Moon Crystal is on it's third season and was confirmed  in January 2017 that a two-part theatrical film adapting the "Dead Moon" arc from the manga will be followed.
