After a very awkward moment in Shido's class where Tohka tries switching genders in an effort to bunk with Shido, the class goes on a field trip to Arubi Island. During the entire trip, Origami and Tohka end up constantly annoying Shido in an effort to win his affections. Meanwhile DEM Industries, an organization with an interest in spirits begins stalking Tohka. Some time later, a massive hurricane appears out of nowhere while Shido and Tohka are on a stroll. Three trash cans strike Tohka, knocking her out in the process while two spirits viciously battle overhead. When Shido tries to intervene, the twin spirits Yuzuru and Kaguya decide that their next battle will be over winning Shido's heart to the latter's dismay. When the two girls follow Shido back to the class holding his arms, Origami becomes enraged over her new competition. As Shido's teacher tries to arrange the girls to be students in the class, Kaguya and Yuzuru explain that they were once one spirit named Yamai and that their contests are in an effort to find out whose personality will stay when the girls fuse and become Yamai once more. Later that day, an incident occurs when the twins drag Shido into the men's bath in an effort to sexually seduce him. Things get worse when Tohka shows up along with the rest of the class.

The twin spirits, still trying to seduce Shido, start cuddling up to Shido completely naked in bed. The situation worsens when one of his teachers walks in on the mess. Later, Shido plans to seal the Yamai twins' powers without letting one of them win in an effort to avoid both the unpredictability of the loser and what would happen to the loser's personality. During their contest, they have Shido coat their backs in suntan lotion ending up turned on from the application. Later, the Yamai sisters team up with Shido to take on Tohka and Origami in a volleyball game in which the winner is the former's team. During the afternoon, Origami is ambushed by a strange mech-like being.

The suspension placed on Origami is finally lifted, we see Kusakabe having some complaints and a new character is introduced into the series. Shido is selected as the organizer of the Ten-Oh Festival, after a spacequake alarm goes off, Shido gets working and a new spirit is revealed, Diva, proves to be more of a challenge than the other spirits. AST interrupts Diva and they go on trying to take her down resulting in her escaping, after Shido encounters himself in a troublesome situation. The transformation of Shido into Shiori begins. The fierce battle to win Diva over begins, but will Shiori be able to accomplish the task at hand or will Diva be more challenging than expected?

Mana finally awakens from her battle with Kurumi. For the upcoming competition Ai, Mai, and Mii prepare a band to compete against Miku's. Origami hears from Ryōko about the usurp mission in capturing Tohka and Shido during the festival. Serving a Maid Café with the Yamai twins employed, Shido (as Shiori again) even hands out posters as the head maid when he and Miku come across and ask "her" to date her though Shiori still annoyed of Miku's arrogance. Shido then finds the bandmates were manipulated and will not perform for the concert. Fraxinus cuts the stage's power to slow things down, but Miku gets the advantage with her Astral Dress. The AST led by Jessica target the Tengu Square until Ryōko and Origami piloting the “White Licorice” interfere. Kaguya and Yuzuru as they are professional, backup Tohka and Shido to perform as best as they could regardless of outside interference.
