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.

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.

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.

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.
