Season 1

Kanami and Hiyori run from the authorities and Hiyori questions Kanami's motives for helping her. They run and hide in the city areas, where they enjoy themselves while Mai, having gained permission from her school principal, starts searching for them using her family's resources.

Kanami and Hiyori use the number that Mai had given them and are met by Rui, a former Minoseki student who agrees to help them by the request of Minoseki's headmaster, President Hashima. Rui allows Kanami and Hiyori to stay in her apartment.

Kanami and Hiyori continue on their way to the meeting point, though Hiyori warns Kanami not to join her if she doesn't have the resolve to kill. They are then intercepted by Ellen and Kaoru who battle them briefly, but Kanami and Hiyori flee when Ellen and Kaoru call in their S-Equipment.

Kanami and Hiyori are approached by Ellen and Kaoru, who claim they are working for Mokusa, a faction of Toji who oppose Yukari. The battle they had was merely to test their abilities. Hiyori remains skeptical, but they are separated by an Aradama swarm.

Kaoru wakes up and reunites with Kanami and Hiyori. Ellen allows herself to be captured by the Elite Guard. Suzuka interrogates Ellen, believing her to be a part of Mokusa since her grandfather is also a suspected member.

Yukina attempts to inject Sayaka with noro in order to increase her power, but Sayaka rejects the injection. On the submarine, Kanami and Hiyori meet Richard Friedman, Ellen's grandfather and one of the leaders of Mokusa.

Akane explains to Kanami and her friends that twenty years ago, a massive aradama named Princess Tagitsu attacked Sagami Bay, causing great destruction. A number of Toji led by Yukari were sent to battle it. Included in the force were Kanami and Hiyori's mothers: Minato and Kagari, respectively.

After a training session, Kanami and her friends are invited to attend the village's festival, where they enjoy the festivities. Friedman explains to them that the village shrine is one of the few left in Japan that possesses noro not confiscated by the Origami family.

Yukari continues her attack on Mokusa by raiding Minoseki, Osafune, and Heijou academies, arresting the directors, and disarming their toji. Meanwhile, Yukari goes to her stockpile of noro and lets it engulf her. In the submarine, Friedman suggests that they flee overseas to escape

Kanami and her friends assault the Origami family shrine while the Elite Guard attempts to intercept them. Ellen and Kaoru team up to fight Yume, Mai and Sayaka face Yomi, and Kanami and Hiyori encounter Maki and Suzuka.

Ellen and Kaoru regain consciousness and meet with Kanami and Hiyori. Working together, Mai and Sayaka are able to defeat Yomi, and Sayaka tells Yukina that she pities her before leaving to join the others. Suzuka stays behind to dispose of Yume's body before she revives as an aradama while Maki goes to find Yukari.

As a result of Princess Tagitsu's defeat, her body dissolves, spreading her collected noro all over Japan and resulting in a sharp increase in the appearance of aradama. This results in the government being forced to temporarily use Toji academy students to fight the aradama.

Mai hears news about how more and more Toji students are being forced to transfer out of their academies by their parents due to safety concerns. Mai's own father expresses his wish to have Mai transferred out of Minoseki, to which Mai protests.

Kaoru is tasked with leading a squad of Toji to investigate sightings of an aradama in the forest, though she doesn't take the assignment seriously due to her lazy nature.

Kanami and her friends celebrate Sayaka's birthday and they begin to discuss the identity of the noro thief. They talk to Akane, who confirms that the noro thief is actually Princess Tagitsu as a human-like aradama.

Kanami, Hiyori, Maki, and Suzuka accompany Akane to meet Yukari, who has fully recovered from her possession and is in charge of protecting Princess Ichikishima.

Kanami and her friends are assigned to protect Princess Takiri. However, negotiations with Princess Takiri do not go well, as she sees humans as nothing more than subjects to be ruled. Kanami suggests sparring with Princess Takiri, since she believes seeing each other face to face is the best way for humans and aradama to understand each other, but Princess Takiri refuses.

One week after Princess Tagitsu's attack, Kanami and her friends are shocked to see Princess Tagitsu publicly reveal her identity, claiming that the great disaster at Sagami Bay was the fault of the Toji. Yukina blackmails the government over their involvement in the disaster, forcing them into siding with Princess Tagitsu.

Having absorbed Princess Ichikishima and becoming part aradama, Hiyori fears losing control of her powers and flees to avoid hurting Kanami.

Having absorbed the essence of the other princesses, Princess Tagitsu begins opening a portal to the netherworld so she can retrieve her true body.
