Sunao had always anticipated falling in love during her junior high school years. However, much to her disappointment, she cannot seem to find any attractive boys at her school. Despite this, Sunao does not lose hope and eventually encounters two charming upperclassmen - Toru, who is caring and sensitive, and Kaoru, who is jovial and welcoming. These boys are part of the school's Magic Club that Sunao decides to join as well. As it turns out, Toru and Kaoru are actually known as "B-apostrophe" and are thieves in search of treasures hidden by a notorious thief from the Taisho Era. According to legend, whoever discovers seven glass balls and solves the seven secrets hidden within them will be rewarded with treasures worth 30 billion yen and a mysterious magic secret. Sunao is taken aback by this revelation but agrees to become part of their team because of her attraction towards Toru and Kaoru. She feels ecstatic being surrounded by such beauties. However, they are not the only ones in pursuit of these treasures. There is someone named "B" who repeatedly obstructs their efforts, and "B-apostrophe" might hold the key to their identity. Sunao finds herself conflicted by her emotions, as she is drawn to Toru but also feels a pull towards Kaoru and even "B" when he interacts with her.
