Reaction! Pretty Cure Elementary is the 18th season of Pretty Cure and the first directed by Lanthanum12 . The plot centers around four middle school aged kids. Reiko, Maki, Saito Katsuko and Goda Suzuki. They make it their mission to stand up to the Antimatter Project. A society of people who plan to annihilate the worlds using Antimatter. Together the Cures must work to collect and protect all the Element Cards before it's too late. The motifs for this series are chemistry, the periodic table and teamwork.


The series starts out with a fairy named Lanthanum arriving to Earth. She warns Reiko about the Antimatter Project. Soon after that all the cures are gathered up.

Much of the series is centered around the Cures defeating monsters called Posti and collecting Element Cards, small charms that hold the powers of each element. When the Antimatter society gains all the Element Cards they plan to unleash a storm of Antimatter to destroy the universe and create a new one so the citizens of Neutrino can go anywhere they want.
