Kazuya's friend Shirou has a tendency to ask girls out without a lot of planning or concern about the outcome. Just when it seems like that approach has finally managed to endear himself to a girl, the looming threat of an amasogi puts a damper on any potential romance.

Taguri asks for help from Takamagahara, who manages the gods that govern Japan. Sunao Sumeragi and her sword-tsukomogami Kotetsu come live at Kazuya's house. Akito and his team go to Mayoika Village and are immediately attacked. They learn the Radical Tsukomogami are comsuming Humans to increase their power. Sunao transfers to Kazuya's school, intent on making him stronger and get closer. Meanwhile at Mayoika, all-out war is planned to obtain Kukuri's shard.

The Tsukumogami from Mayoika Village arrive on a flying boat. During the confrontation with the Mayoikan Miurahi, who carries the shard from the goddess he killed, Kukuri uses her last resort to defeat him. To everyone's shock, Azami interferes and her true intentions are revealed, putting Kazuya in a very hard spot.
