The Garden of Sinners: A Study in Murder – Part 1 (空の境界 第二章 殺人考察（前）, Kara no Kyōkai Dai-Nishō: Satsujin Kōsatsu (Zen)^?) is a 2007 Japanese animated film produced by ufotable based on the Kara no Kyōkai novels by Kinoko Nasu. It is the second installment in the series, preceded by Overlooking View (2007) and followed by Remaining Sense of Pain (2008).

Mikiya first meets Shiki in a white kimono during a snowing day. Later on, at the high school freshmen ceremony, Mikiya sees Shiki in the crowd and chases after her, introducing himself to her. At night, Shiki stumbles onto a fresh corpse of someone killed in a traffic accident, the blood still flowing. Kneeling, she applies the blood on her lips as lipstick and smiles. At school the next day, Mikiya discusses Shiki's choice of dress, a kimono, stating that it must be cold. Shiki replies that she will simply wear something over it when it gets colder, and Mikiya suggests a jacket. Shiki later on takes Mikiya's suggestion and buys her trademark red leather jacket. At night, a man stumbles as he runs in fear from an unseen attacker, who kills him brutally with a knife. The next day, Mikiya tells Shiki about the murder, saying he has an inside source as the murder is not on the news yet but Shiki is displeased that Mikiya is talking about something like that during lunch.

The police discover the fourth corpse, the school reacts to the news by prohibiting all after school activities. Shiki is one of the few people left in the school by this time, but bumps into someone she does not know, who reprimands her by asking her if four times isn't too much, even if she is irritated. Shiki refuses to reply. It is raining outside, and as Shiki waits at the entrance, Mikiya comes up behind her and offers her an umbrella. Startled, Shiki refuses, saying she has someone coming to pick her up. The two wait there in silence, until Shiki can no longer stand it and suddenly asks Mikiya where he was the whole time, and he replies saying that he was in holding a farewell party for an upperclassman, Lio Shirazumi, that was dropping out of school because he found something to do. Mikiya invited Shiki as well, but Shiki did not think he was serious. At night, Shiki finds the fifth corpse, but simply remarks "the fifth one" unemotionally.
