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.

Momiji and the TAC take refuge in Sakura's apartment in order to avoid the goverment long enough to find a way to handle the Arigami. Sakura confirms Kunakida's suspicions--the US can't help until they are specifically asked for assistance by the Japanese government, due to the terms of the joint-treaty. The TAC hopes that the apartment is inconspicious enough that they will be able to continue their Arigami research without disturbance. Unfortunately, that isn't the case. Murakumo shows up. Yaegashi is wounded trying to protect Kome, and Momiji is carried off by Murakumo.

Murakumo takes Momiji back to the place where Kaede and Susano-oh are residing. He hopes to use Momiji to get to Kaede, who he now wants to kill. His plans are interrupted by Kusanagi. A battle ensues. Kaede saves Momiji, whose mitama is lost (but retrieved by Kusanagi.) The giant mitama is Susano-oh's resting place begins to shake violently. Thanks to his new mitama, courtesy of Momiji, Kusanagi is able to fly them

The giant Arigami buds are blooming, causing mitamas to fall to earth. The mitamas cause all whom they touch to turn to plants...

Momiji screams in pain as the Kushinada pulse is turned on her. Kaede hears her screams, but says that it is ""too late."" She melds herself into Susano-oh's mitama in order to protect him from Murakumo, who is still attacking.

Murakumo suffers a few blows from Kusanagi before burying one of his heads into Susano-oh. Murakumo laughs, announcing that he has won, as he begins to drain Susano-oh's energy. Kaede only shakes her head and calls him a fool. Murakumo continues to feed off of Susano-oh's power until his mitama grow to be huge. Then suddenly, his mitama shatter. As Murakumo is left writhing in pain, Susano-oh finishes him with an energy bolt.

The children of Japan can hear the Kushinada's pulse, Momiji's song, and are starting to sing along with it.

Momiji has almost completed the matsuri. The members of the TAC note that they all feel warm and happy
