Aragne: Sign of Vermillion

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.

On their way home from high school, Tamahi and some classmates are shocked as they witness someone fall from the rooftop of nearby apartment. Panicked and confused, they rush to the building only to find it deserted. As Tamahi wonders about this, she has the uneasy feeling they are being watched. What is the strange presence around her…

November, 1998: Shiki meets a boy named Tomoe Enjou, a runaway who claims to be a murderer. Shiki allows Tomoe to use her apartment as his hideout, but one day, Tomoe sees his mother whom he's sure he's killed.

July, 1998: One night, Mikiya helps a girl lying doubled over with stomach pains. Around that time, a number of dismembered bodies are found throughout the city. The murder victims are torn apart so badly that they don't seem like the work of a human.
