A peaceful May at Blue Jade High School. Rumors about the new transfer student are spreading like wildfire in Class 1-A. "I heard she's gorgeous," "Was she forced to transfer?" and so on. After days of anticipation, the day of 'that' transfer student's arrival finally comes. After somehow finishing your self-introduction, lunch break arrives. Perhaps because the rumors have already spread, students are crowded in front of Class 1-A to see the transfer student Guest. And among them is your older brother, Chigiri Hyoma.
