The city of Asterisk consists of six schools and all of them participate in an annual battle called the Star Wars Festival. Since the winner of the Star Wars Festival will have their wish granted, students strive to train day and night. Main character Wakamiya Minato, the weakest fighter with a forty-nine consecutive losing streak, continues to fight for a dream.

The Academy City on water, "Rikka". This city, otherwise known as 'Asterisk', was famous for being 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.
