Noticing Ichiko doesn't seem to get along with the other girls, Ranmaru tries being friendly with her, but her pride rejects her offer. The next day, a zealous classmate named Akane Tenge and her gang kidnap Ichiko and take her to the old school building with a plan to put her in her place. Ranmaru arrives to rescue her but as Ichiko manages to sneak away, the building collapses with Ranmaru inside it. As Ichiko becomes conflicted over whether to save Ranmaru or not, she recalls when she was younger when her best friend turned against her over a boy, which has haunted her to this day. Telling her to get over her cowardness, Momiji extracts some of Ichiko's Fortune, which Ichiko gives to Ranmaru, allowing her to escape. After the incident, Ichiko lets Ranmaru use one of Momiji's gadgets to learn about her past trauma, which caused her to have a fear of getting close to others. After hearing her story, Ranmaru makes a promise to never betray Ichiko and the two become friends on a first name basis. (thetvdb.com)
