Things get even more confusing for poor Momiji when a man named Mamoru Kusanagi arrives, but when she learns that he is there to protect her from these strange monsters (Aragami), she feels safer. Little does she know Kusanagi hasn't decided to save her or sacrifice her.

Meanwhile, the TAC rush to the scene with an experimental creation that may defeat the terrible Aragami.

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.

Rule-altering TAC member Kome Sawaguchi is angry when she is stuck babysitting the newest addition the team, Momiji Fujiyama. Soon the team discovers that Momiji's blue seed can track down Aragami and something terrible may occur soon.

Angered Momiji sets out to rescue a kidnapped little girl. Unfortunately, the girls father is a man who studied Kaede (Momiji's sister), and the kidnapper is asking for extra material.. Material that can help the Aragami defend themselves from Momiji.

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 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!

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
