Five years previously everyone in Ōtsuka village died in a plague, but there were 3 survivors, Shino Inuzuka, Sosuke Inukawa and Hamaji. They took shelter in a church near another village, which happens to be near a dark and dangerous forest. The church, as well as the survivors, are viewed with suspicion by the villagers. Now the Imperial Church comes in search of "Murasame" the demon blade that contains "life" which Shino possesses.

Shino and Sousuke travels to the city to find Hamaji.

Shino and Sosuke was reunited safely with Hamaji at the Villa. Shino told Sosuke that they were saved by Satomi Rio five years ago. Satomi gave Shino and Sosuke their marble that represents them as one of the eight beast and asked them to gather all eight of them.

Due to the new moon, Sosuke sleeps for an abnormally long time while Murasame becomes strangely quiet. Shino then bumps into a white-haired, red-eyed girl from the Snake Clan, Mizuki Ayane, that occupies the other half of the abode. In an attempt to become friends, Hamaji sends Shino to the other side with a basket of flowers, to which he angers Mizuki Ayane's guardian god, Hibiki. Shino is saved by sosuke, who almost cuts off his arm as a peace offering, and is rescued by Ayane. The four of them start to talk about themselves, which compels Ayane to befriend Hamaji. There is a town festival, however, Hibiki is reluctant to let Ayane out of her sight, but eventually gives her consent to leave the house, so long as one of the Osaki foxes remain by her side.

Shino shows interest in a incedent that was reported in the newspaper. Apparently six villagers were visiting Perquisite Mountain in search of a new water sorce, but become lost. A "beautiful woman" appeared before them and showed the villagers the way back to the village, where they died of an unknown illness. Sousuke searches for Shino, who has gone to the mountain to investigate. While on the mountain, Shino's and Sousuke's beads begin to glow. Destracted by this, Shino loses his footing and falls down, dropping the two beads. While waiting at the train station, Sousuke meets Kobungo, who decides to join Sousuke. After losing Sousuke's bead, a monkey deity appears before Shino and gives him a huge rock of gold. A group of traveling musicians come to the village to perform during the festival, and it is revealed that one of the musicians is Asakeno.

The villagers have discovered the gold the monkey god gave Shino and has forced him and his friends to take them up the mountain. That forces Akane to make return to the mountain where she spent her childhood.

On the train ride home Shino meets an old friend to the surprise of Sosuke.

Hamaji is moving to an all-girls school dorm. There's a rumor about the guardian of the school and Hamaji asked her roommate if she have seen the guardian of the school but then she said no. Shino encountered the guardian and apparently isn't every good in dealing with cute dolls. After Shino re-encounter again with the guardian this time with Inusaka Keno and also Sosuke, they relieved that they were only worried about Hamaji. The next day, Hamaji's roommate mentioned about how great Hamaji's friends are and then gave an excused to go back to the room. Hamaji then met some girls inviting her for lunch and revealed that Hamaji stays alone. Hamaji ran back to her room seeing a doll on the bed and to her feelings, that was her roommate and thanked her.

A man that resembles Sosuke has been spotted in the Imperial Capital; this has Keno up in racing around the city to exact his revenge.

Murasame starts going crazy from blood loss after Shino is shot in the neck. Shino then reverts back to his supposed 18 year old self.

Kohaku returns to her abode, and seemingly "devours" her friend. The next day, she wakes up in a blood-stained room and news about the mysterious death of one of the Zuikou Mansion workers spreads. Shino wakes up, still in his eighteen y/o body, and leaves for the church, where Kohaku escaped to. After Kohaku's explanation of her life story, she starts to grow a pair of rigid wings while Sosuke and Satomi attempt to console her. Shino appears and reveals Murasame as a sword, calling Kohaku an "angel from a picture book," rather than the monster she saw herself as. Shino then falls asleep and once again returns to his child form of a body.

The Church is forcing Satomi to bring Shino before the Elders. To make matters worse, the man that looks like Sosuke shared with Shino some devastating secrets.
