Chikane and Himeko share the same birthday and it's rapidly approaching. On the day of their birthday, the Orochi are awakened and at first Sōma attacks Himeko who is the Solar Priestess. Eventually, he comes to his senses and is able to fight back against another one of the Orochi, the Second Neck, Sister Miyako. Chikane and Himeko share a kiss.

The story of the Orochi and the Priestesses is revealed to the unsuspecting Solar and Lunar Priestesses. Later, Himeko contemplates on leaving the town, but first a fight ensues between the Priestesses and the Third Neck of the Orochi, Girochi. Finally, before things get too out of hand, Sōma comes to the Priestesses aide.

With nowhere else to stay, Chikane offers for Himeko to stay at her mansion for the time being. Later, Kazuki Ōgami reveals more about the Priestess's past and what they are meant to do to protect the world from the Orochi. Also, the Sixth Neck of the Orochi, Nekoko, attacks the Priestesses.

Sōma invites Himeko to the amusement park on a date and Chikane tries her best to help Himeko prepare for her outing. While on their date, Tsubasa, the First Neck of the Orochi, attacks the couple as Sōma tries his best to protect Himeko.

Sōma initially gets defeated by Tsubasa in their first fight and Tsubasa promises to return again. In the meantime, Sōma trains to get even stronger for their next fight. It is also revealed that Tsubasa is in fact Sōma's biological older brother.

Some of the past is revealed on when Chikane and Himeko first met and how they became friends. Later, the Priestesses continue their training to become stronger, but fail once again. Finally, Himeko goes on her second date with Sōma.

While Sōma and Himeko are on their date, it begins to rain and they take shelter in an abandoned warehouse. Meanwhile, Chikane has an encounter with the Second Neck of the Orochi who also begins playing with Chikane's feelings for Himeko. Later, the Third, Fourth, Fifth and Sixth Necks of the Orochi all attack Sōma while on his date with Himeko. After the fight, Sōma kisses Himeko.

During yet another outing with Sōma, Himeko searches for a present to give to Chikane since she knows something is not right with her. Upon returning to Chikane's mansion, Himeko is shocked to find that the Lunar Priestess has joined the Orochi, becoming the Eighth Neck. Chikane sexually assaults Himeko.

After the previous night, Himeko is still shaken up by what happened between her and Chikane. Later, her friend Makoto Saotome comes back to school and their friendship is finally healed. Meanwhile, Chikane begins fighting and in the process defeats each of the Orochi one by one until the only one left is Sōma.
