To the dismay of the TAC, Kaede Kunikida suddenly disappears. Meanwhile, the young school child Momiji Fujiyama is attacked by a strange man, hellbent on killing her. But why is he doing this?

After surviving the attack, Momiji's school is filled with monsters, but the strangest thing of all is that people think she's some sort of princess.

TAC Member Yoshiki Yaegashi feels that the others seem to help out a lot more and that he is not needed, and when kind-hearted Momiji tries to help out, she discovers something about him that she could've lived without knowing.

After trying to help Yaegashi restore his confidence, the two set out to track town an Aragami.

The prime minister grudgingly decides to sacrifice Momiji in order to save Japan from the growing Arigami infestation. Momiji, still grieving over the loss of Kusanagi, accepts her fate and goes with the government to be sacrificed.

The TAC isn't quite ready to give up on her just yet. Takeuchi and Kome go to rescue Momiji. Momiji refuses to go at first, saying that this is her destiny. But Takeuchi slaps some sense into her (literally) and reminds her of what they are fighting for.

The three TAC manage to escape thanks to some unexpected help from Sakura and her pink sea creatures. As they are leaving, Momiji's mitama begins to glow. She can sense Kusanagi!
