The episode starts with Kisaragi fighting a Tautai at school but failing to defeat it. Kisaragi wants to help in the fight against the three strongest Taytaya but Mashiro believes that only Yuri has the power to do this. Red, glowing spiders are shown weaving webs everywhere around the school. Kisaragi assembles a group of girls from the dormitory while Mashiro and Yuri who is disguised as a girl enter the dormitory to face the Tayutai there who turns out to be Nue, one of the three strongest. At first Mashiro seemed to be losing the fight but Kisaragi orders the girls she gathered to get rid of the spiders after which Nue is weakened. She had noticed that Nue was unable to use her powers in water so she threw water on her and easily defeated Nue. Kisaragi reveals that she had sensed the spiders along with the group of girls she gathered and had already realised that it was a trap. Nue the reverted to her original form and turned out to be a little girl. Kisaragi promised to give Nue whatever she wants if she agrees to stop fighting. Nue agrees to this and the episode ends.
