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.

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.

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.

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.

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.

Dire Tokyo is being stalked by mutated dogs, but the TAC and their friend Kusanagi are doing nothing to defeat them. Soon the group discovers that they are being mysteriously killed, and to catch both the dogs and the killer, Kusanagi brings Momiji out on what he told her was a date, little does she know it's a plan to save Tokyo.

Another Aragami is again terrorizing Tokyo, and this time it's a fire-breathing frog who has his eyes on the subway system. When Momiji confronts the Aragami, she meets Muramuko, an evil man who almost brings her life to an end. Kusanagi arrives just in time to give her mouth-to-mouth, or what she considers 'a kiss', and faces off with Muramuko.

Momiji is horrified when Sakura is transferred to her school, and to top it off, she finds that Sakura and *her* love Kusanagi are spending time together. Meanwhile, girls at Momiji's school are being found dead, their blood sucked from them. That sure ices the cake!

Poor Momiji Fujiyama is having a terrible time trying to keep up in school AND work at the TAC, but when her wounded love arrives at her window needing treatment, she happily takes him into her home. Meanwhile, the TAC investigate a strange centipide that has a habit of wrapping itself around large skyscrapers and leaving it's (icky) skin all over the place.

The TAC decides to lend love-struck Momiji a hand with dating advice and tips on how to confess her love, but everything goes wrong and she is called to witness the rebirth of the Aragami God Susana-O and the return of Kaede -- her sister.

While Kaede and Muramuko rush away with Susana-O, trees all over Japan begin to wither and die, causing a national uproar. Meanwhile, at the resort of Nara, a new type of Aragami are terrorizing the land by polluting the air with toxic pollens. Disheartened Momiji, distracted Yaegashi and the rest of the TAC team set out to destroy the pollen monsters with their newest invention.

The team journeys to the countryside to investigate more on the reappearing Kappa sea monster, meanwhile Momiji is concerned over a classmate of Kaede's words. How can a being such as perfect as Kaede be defeated by her? How can *SHE* win!?

Kunikida heads out to investigate the death of his old friend, and is greeted by his young wife who holds a deadly secret. Meanwhile, deformed bodies begin piling up as sightings of the ""Thousand Year Nun"" (a strange woman who would stay young forever by devouring the flesh of a mermaid) are reported.

Distraught Kunikida becomes obsessed with his work, and the beautiful Takeuchi tries to help him, but fails to completely comfort him. Meanwhile, both Momiji and Kusanagi are worried about the ritual that is soon to take place, the ritual that will increase the power of Susana-O.

When Susana-O's power disturbs Nozuchi, a powerful Aragami, Sakura's past is dug up, revealing that Nozuchi killed her mother long ago. Momiji Fujiyama, along with the help of the TAC, come to the aid of Sakura, but are helpless to prevent Nozuchi from swallowing Sakura. Inside the stomach of the monster, Sakura makes a horrifying discovery -- her mother is still alive.

After the powerful Kaede envelopes an abandoned city in a dome of energy, Kusanagi wonders in and finds himself trapped, causing Momiji to come in after him. But when Kusanagi is overtaken by his daydreams, Momiji is helpless to save him.

As reports of monster sightings and complaints of giant plants appearing everywhere busy the TAC, Kunikida heads off to Izumo, hoping he can uncover this mystery. Meanwhile, Momiji finds her mother, Moe, but begins having thoughts of Kusanagi, who is off fighting Susana-Oh, Kaede, and Muramuko.

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.

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!

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

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. Kunakid

It's dawn and the TAC is preparing for the final battle. The team prepares the Kushinada pulse amplifying machine while Momiji prepares herself for the Rite of Matsuri. With less than an hour until the solar eclipse, Kaede begins the ceremony by touching a sword to the field around Susano-oh. Susano-oh begins to mutate into a big, ugly nasty beastie. Meanwhile, the Prime Minister is being persuaded by his aide to lie to the people of Japan to keep them calm and under control. The Minister goes on television, but instead of lying to the people, he tells the truth. He informs them that the problems have been caused by an ancient race of monsters called the Arigami, and that the Kushinada is the only one with the power to stop them. Momiji comes onto television, requesting that the people of Japan give her a chance to live. She wants to try an alternate method to kill Susano-oh, but if her plan does not work, she will accept her fate and sacrifice herself. Momiji begins the rite of matsur

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
