After being sent to Tokyo, the Aragami-target Momoji discovers that she is now under the care of the TAC. She knows these monsters are terrible, evil things, and really wants to help, but can't find out how to.

The TAC soon discover that their base isn't as safe as they thought when an Aragami breaks in and attacks.

Kusanagi is outraged when Mrs. Matsu-Daira sees Momiji as a live specimen, free to experiment on her. Just as Momiji is about to confront Kusanagi on the threat he made to the lady and her son, a strange jellyfish emerges from Tokyo Bay and things heat up.

Sakura Yamazaki has just returned from her stay in America, and the priestess considers Momiji Fujiyama an enemy. Sakura thus challenges Momiji to a singing contest -- at a studio with a number of Aragami attacks.

The battle rages on as Momiji's mother, along with Kunikida, finally confront Kaede and Susana-Oh. Meanwhile, Momiji and Ryoko find Kusanagi fighting, but before they can help him, he is defeated by Muramuko.

Kusanagi pays the prime minister a visit and delivers a special package--a cell phone from Kunakida. With it, Kunakida tries to convince goverment officials that the TAC can eliminate the Arigami without sacrificing Momiji. He asks that they at least give the TAC a chance to save Momiji's life. The prime minister reveals that that Momiji's pictures were released to the press by an Arigami spy in the government, whom they have been unable to identify.

Meanwhile, Japan is in an uproar. Volcanos are erupting everywhere and plants continue to grow at incredible rates. The people want the Momiji to be placed in custody, and they are angry with the goverment for being unable to do so.

Progress continues on the Kushinada pulse, and the TAC discovers that the secret to the Kushinada's blood is somehow involved in the strange melody that both Momiji and Kaede resonate. Momiji remembers that Kaede spoke of the rite of matsuri, and asks to be taken to the place where the ceremony is held.

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
