The existence of magic started to be known and recognized, but due to its origin, the disaster that is known as "Magic Calamity", people still avoid themselves away from it.
The conclusion of political debate about whether to accept or reject magic can still not be reached. Many who had gotten hold of the power hid their existence and advanced their desire from the dark. Among them, the existence of young girls who fight using magic and magical weapon became a hearsay.
They are the beautiful goddesses who are trying to change the dark existence of magic into the shining light of peace. The girls are known as "Mahou Senshi" (Magical Warrior).
Mashiro Haruka is a female student who goes to the first school to integrate Magic Study into its curriculum, Kokusaikyoudou. She studies Alchemy at school and she managed to become a Mahou Senshi who protects people from magical threats, Emeroad Finé.
Haruka uses Emeroad Lapis that her father, who was also an Alchemist, left behind to transform. At Kokusaikyoudou, she learns how to fight using her transformation form from Tachibana Arisu and Kagashima Itsuki.
Together with Mahou Senshi Exeed Knights who has enrolled at Kokusaikyoudou, they work together to protect people from Magical Calamity. One day, a transfer student named Kurou Kasumi appears before Haruka.
That is a fateful meeting that triggers Haruka and Kasumi's destiny
