This idea came up as I was thinking about expressionist composers and the screwed up operas they write. Anyway:
Abstract: On the run after he killed Sora (on the fly/accidental death, not premediated murder), Yamato meets up with Jyou, a shady character who offers to hide him -- for a price. The price? Jyou is lovestruck with Hikari, and wants Yamato to lure her to him. As Yamato begins his quest, his past catches up to him in the form of Taichi, one of Sora's best friends, and Takeru, the little brother Yamato had abandoned ten years earlier. To make matters worse, Hikari turns out to be Taichi's one and only sister as well as Takeru's fiancee. Also, Yamato is mentally breaking down from the guilt...
Characters: The ones in the abstract. May include other characters (such as the police).
Setting: Pre-modern society
Genre: Angst. Lots of angst.
