One day, the bright red sun stopped shining, causing the "Breakdown Phenomenon"—the destruction of Arata Kasuga's town and the disappearance of the people inhabiting it. All, however, is not yet lost; by utilizing the magical grimoire given to him by his childhood friend and cousin Hijiri Kasuga, Arata's world gets artificially reconstructed. In order to investigate the phenomenon, Lilith Asami appears before Arata, whose artificial world suddenly disintegrates. He is given two choices: hand over the book, or die. However, Arata chooses the third option—enrolling in the top-secret magic school Royal Biblia Academy, where six other magical users await him. Together with Lilith, these six form the Trinity Seven, the elite of the school who each bolster their own power and skill. With the ambition to save Hijiri and the help of his newfound friends, Arata stops at nothing to prevent the destruction of his beloved hometown and to bring his best friend back.

Futaba Yoshioka used to be an attractive and popular middle-schooler—well liked by the opposite sex, but ostracized by the girls. Nevertheless, she was able to brush all that off, because the only opinion that truly mattered to her was that of Kou Tanaka, a classmate with whom she shared a shelter from rain once, followed by quite a few other precious and significant memories. She even succeeded at making plans to meet with the quiet and innocent boy at the summer festival, but a simple misunderstanding, and Tanaka's subsequent disappearance, left her walking the halls of her school friendless. Now in high school, Futaba is not your typical adolescent girl. Determined to become a class favorite this time, she avoids all unwanted attention and, instead of acting cute and feminine, only stands out through her tomboyish behavior and disheveled look. But still, her world is soon turned upside down when the only boy she ever liked unexpectedly comes into her life once again—except he goes by the name of Kou Mabuchi now, and it is not his name alone that has gone through a sea change.
