|Part 1: Panorama|
This starts off very slow, with Mikiya Kokuto talking to Toko and Shiki about the recent case of girls committing suicide...
Shiki says she saw 8 ghosts floating around a tower, and declares that this 8th suicide will be the last one for a while... then they go into this long discussion about panoramic views and how seeing your world from so high above makes you want to jump down...
Then Shiki goes to the tower and talks to/fights this ghost that's behind the suicides or something I think? Also Shiki has split personalities, and the one in command during this fight is the boy version, SHIKI.
Part 2: The First Homicide Inquiry
This chapter switches between Kokuto and Shiki as the protaganist... Shiki's other personality starts to come out more around him, and they start going on dates. Later SHIKI reveals to Kokuto that she's starting to be at odds with her other self recently... SHIKI represents the things that Shiki secretly wants deep down, but keeps repressed... Shiki is trying to murder everything in her life that would make SHIKI want to come out.
oh and also some stuff about homicides.. Kokuto is related to an investigator on this case and he starts to suspect one of the Shiki's, then he goes to ask her and finds Shiki standing near a bloody corpse with an evil grin... this whole chapter spans several years btw.. after this happens, Kokuto keeps watch on Shiki because he wants to believe she didn't do it (even though she's telling him not to trust her).. and that happened to be the last time in years that any Shiki-related murders happened.
