With strange events occurring at Reien Girls' Academy during winter break, Azaka Kokutou, a student and apprentice mage, is sent by her master to investigate. It turns out that another mage has been stealing the students' memories using fairies that, despite her magical talent, are invisible to Azaka. So Shiki Ryougi, an acquaintance with special eyes who can see what Azaka cannot, is also sent to the academy to help with the crisis. 

However, the two have trouble getting along, mainly due to the fact that Azaka views Shiki as her romantic rival. But when the fairy situation quickly spirals out of control and more layers of the mystery are revealed, Azaka must learn to work with Shiki in order to save her classmates.

In February 1999, a string of murders has Shiki Ryougi and Mikiya Kokutou on edge. These crimes share a disturbing resemblance to a similar set of homicides from 1995, when Shiki and Mikiya first met, and awaken a dark, murderous desire that has laid dormant within Shiki's soul ever since then.

With Shiki under suspicion due to her involvement in the past killings and supposed resemblance to the killer, she and Mikiya set out to find the true perpetrator. In the midst of their separate investigations, Mikiya grows increasingly concerned with Shiki's well-being and hurries to find the one responsible in order to protect Shiki from her own impulses. With the lead he receives from his cousin, police investigator Daisuke Akimi, Mikiya is led into the underbelly of Mifune City, as the salvation of Shiki's soul lies in his determination to prove her innocence once and for all.

Mikiya Kokutou gives Shiki Ryougi a cat to watch, as he will be away for a little while. Though Shiki protests, he leaves the cat anyway, and Shiki is stuck trying to understand her new feline companion. But as luck would have it, the cat seems to have taken a liking to Mikiya and misses him.

Later in another part of the city, Ririsu Miyazuki visits the place where her dear friend committed suicide. She intends to end her life as well, but she meets Fujino Asagami, a blind classmate with a traumatic past. Though the two girls don't have much in common, Asagami reminds Miyazuki of her lost friend and helps her understand her pain.

Two months later, Mikiya elects to celebrate New Year's with Shiki instead of his family, which makes his sister Azaka very upset, leading to her spending the holiday with her school friends. As the snow begins to fall, Mikiya reflects on what he wishes for most of all: that Shiki's life be filled with happiness.
