Cossette no Shouzou, Kara no Kyoukai 7: Satsujin Kousatsu (Kou) Recommendations
(Of course I mean the whole KnK series, not just the final movie.) These titles are similar in many ways. First, they share a gloomy atmosphere, occult themes, rivers of blood & lots of other horrors. Second, both are truly stunning artworks featuring all modern achievements in the field of animation. Third, the plot: the two stories are equally unpredictable, with unexpected sharp turns and mind-blowing endings, and also connected by themes of love, sacrifice and redemption. And last — but definitely not least — the brilliant music by Yuki Kaiura.
