Shido goes to Origami's apartment to look for Hermit's puppet, Yoshinon, who was lost during the last fight, and Tohka talks with Reine about her feelings for Shido.

To get ready for his date with Kotori, Shido goes swimsuit shopping with Tohka and Yoshino. Meanwhile, Origami finds out more about Ifrit.

Shido and Kotori enjoy their date at the amusement park until they are interrupted by Origami.

Shido wakes up by the troubles of both Tohka and Yoshino and somehow resolves it, meanwhile Origami got suspended for two months by the AST. While eating their breakfast, Shido receives a text from Origami and they discuss about the event that happened a month ago, While cleaning the room of Shido, Tohka notice a suitcase (for their school-trip) that is a resemblance of a drama sequel on the television. Tohka got worried and rushes to find Shido with Origami. While Shido tries to make it up with Tohka by getting her some kinako bread on the way home he notices that the lock of his suitcase was broken, so he went out to meet up with Origami again. While Tohka imagines another scheme of the show she rushes again to find Shido. And this time he caught Shido and Origami together and imagines that Shido is abandoning her for Origami. Tohka gets jealous gaining some of her powers and runs off while carrying Shido's suitcase. Elsewhere, Tohka's unsealed power starts to create a spacequake. Shido rushes to find Tohka and finds her in their special place and Tohka (misunderstanding everything) tries to prevent Shido from leaving but he explains that all is a misunderstanding, while Tohka cannot control her powers and hit Shido with shockwaves but Shido manages to seals Tohka's power again. While Isaac and Ellen are scheming a plan for Tohka, meanwhile Kurumi plots to kill the first spirit.

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.

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.
