Gakusen Toshi Asterisk
The Academy City on the water, Rikka (otherwise known as Asterisk) is the world's largest stage for the integrated battle entertainment, "Star Wars Festival." The young boys and girls of the "Starpulse Generation" belonging to the six academies made their wishes with Shining Armaments in their hands, vying for supremacy Amagiri Ayato is one of them.
Ayato arrived at Rikka at the invitation of the Student Council President of the Seidoukan Academy, Claudia, and right after that he incurred the wrath of the "Petalblaze Witch" Julis, and ended up having to duel her.
The greatest academy battle entertainment, begins here!
