Chisato Matsui

Girl #19 Chisato Matsui is one of the class of third-year students at Shiroiwa Junior High School in Shiroiwa, Kagawa Prefecture. The novel describes Chisato, a member of a non-distinct group of girls referred to by the novel as "the neutrals," as "always quiet and withdrawn." Chisato is a petite girl with long hair. She had a crush on Shinji Mimura and in the Manga, she and Yuka were apparently "Boy crazy".

Chisato was one of the girls who teamed up with Yukie Utsumi and the others at the lighthouse. She cooked the meal, along with Haruka Tanizawa, which made the others suspicious of her when Yuka Nakagawa was poisoned. When the girls all became paranoid and panicked, Satomi Noda grabbed the uzi, and when Chisato moved to get Yuka's gun, Satomi shot her three times in the back. In the film, she also accuses Yukie of poisoning the meal in order to run off with Shuya Nanahara alone before grabbing a gun. In the Manga, Chisato is worried Satomi will convince the others that she killed Yuka. So Chisato grabs her gun and points it at Satomi to stop her. Satomi suddenly panics and shoots Chisato in the stomach and she falls to the floor dead.
