Ryota had been suffering from a nightmare. It was physically and spiritually coming to the limit physically and daily to compatibles writing doujinshi and socializing with Yuriko. A member of the monster club who seriously discusses this theme "the greatest invasion in history" as a theme. Ryota realized that he could not do activities with a passionate feeling in his enthusiasm confided Yuriko to the existence of the monster club and decided to confess to put distance. It looks like a scene where Dan confesses the identity of Anne! But "Do not you come and visit us because you do not have a parent at the trip," Ryota shakes as early as possible to Yuriko-san's invitation! what will you do! What? Ryota's last battle begins now, like Seven!
