Tayang pada 25 Juli 2014
The Defense Four are assigned as the JNR idol Noa Kashima's guards during a performance on the beach. After guarding her against a fan at the station, Takayama faints. As thanks, Kashima gives him her stamp collection book. During a practice session, flash paper (Nitrocellulose) is burnt as a threat to Kashima's performance. The following day, during the performance, the criminal, disguised as a member of staff, attempts to run on stage and stab Kashima. Thanks to Iida's quick thinking, they manage to play it off as a performance. Takayama gets stabbed but is saved by the stamp book in his chest pocket. In the end, it seems that Kashima develops romantic feelings towards Takayama. (Source: Wikipedia)
