Lucky Clover wants to recruit Yuka as a member. She is strong and has the potential to become stronger. Yuka, Naoya, and Keitaro volunteer with the kids at an orphanage where Teruo, the boy Naoya saved, lives. Strangers warn the police to quit investigating the “incidents” because they are accidents. Meanwhile, those same strangers continue to follow Yuka and her friends as they head to an amusement park. The strangers seem to be conducting experiments of some sort. Keitaro tries to make a move on Yuka and gets rebuffed. She runs off and is followed by one of the strangers. She is approached by Lucky Clover and is forced to fight to show her strength. Masato and Takumi come to her aid.
