One of the anime projects to commemorate the 20th anniversary of the Precure franchise, this will be a direct sequel of Mahoutsukai Precure! aimed at grown-up fans of the anime. 

Mirai Asahina, a very curious 13-year-old girl with a love for mysterious things, met a young witch named Liko during spring break.
Led by miracles and magic, Mirai and Liko both transformed into the Legendary Witch "Precures"! 
Working together with Mirai's treasured teddy bear Mofurun and Ha-chan, a fairy born from the "Linkle Smartbook", they tried to repel the chaos that was encroaching upon the "Magic World" and "Magicless World (Human World)". However, that involved the separation of everyone. 

After being miraculously reunited a few years later, Mirai and the others begin to take steps towards their futures in their respective worlds. Mirai is a college student in the Magicless World. Liko, who returned to the Magic World, is a teacher at the Magic School. Mofurun, as always, is at Mirai's side. Ha-chan exists far away, watching over the world. 

However, a new disaster threatening the Magic and Magicless worlds has appeared... 
Due to signs of the coming disaster, Mirai and Liko reunite for the first time in months. While attempting to resist this mysterious enemy, they both come face to face with not only their past, but their future. With the magical words "Cure Up RaPaPa!", their exciting tale is once again set into motion!
