Middle-schooler Akuru's childhood friend Shinto (whom she has a crush on) has given her a carefully constructed Aquarian Age deck for her birthday. Now Shinto will teach her to play Aquarian Age, and Akuru will become an ever stronger card player! This is the story of their daily school life as they play Aquarian Age with their friends!

This is the continuing story of Akuru, her childhood friend Shinto, and all the other friends they've made through the card game Aquarian Age. Together, they all enjoy holidays, school life, and Aquarian Age, but will Shinto ever notice that Akuru wishes she were something more than his friend?
