Laura appears in the nick of time to protect Ichika and Madoka flees. Some time later, Charlotte is assigned to perform some escort job and with the other girls all busy, Ichika offers himself to assist her. While dealing with some attackers, Ichika protects Char from an explosion and back at the academy, his Byakushiki is confiscated after displaying some abnormal behavior. With instructions to not fill in the others about it, Char decides to watch over Ichika by herself as long as he is defenseless, but she comes into another predicament when her panties vanish mysteriously. Charlotte then discovers that changing her underwear does not solve the problem as it vanishes as soon as she puts it on, thus she is forced to keep going commando even at the risk of Ichika figuring out. Noting that something is wrong with her, Houki, Cecilia and Lingyin manage to have her reveal all the truth and the three start fighting for the right of becoming Ichika's bodyguard until Tatenashi appears to reprimand them for causing a commotion inside the school. Just when Charlotte decides to reveal the truth to Ichika, Laura appears and confirms that her panties had returned as the interference causing malfunctions of both Ichika's and Charlotte's IS had subsided. Back at their room, Laura points out to Charlotte that all her troubles could be averted if she had put on a bloomer instead of panties, much to her chagrin.
