Kara no Shōjos gameplay primarily revolves around reading dialogue with other characters and making choices that affect the outcome of the game. At certain points in the game the player character, Reiji, is tasked with investigating crime scenes. During these investigation sequences, the player must examine these scenes to uncover evidence and depending on the evidence found, the course of the game can change. After collecting evidence, the player must put it together during inference sequences, in which Reiji must find the best answer from the clues obtained before and answer questions about the case. It is possible, however, to fail an inference sequence by missing a given piece of evidence during a prior investigation; this in turn affects the game's ending. The game also features a travel system, through which the player can traverse between different locations in Tokyo. The player can only use this a limited number of times per day, and only on certain days.

Set in a post-World War II Japan during 1956, Kara no Shōjos story revolves around Reiji Tokisaka, a private investigator who is investigating a series of grotesque murders on the request of his former colleague/best friend, Kyozo Uozumi of the Tokyo metropolitan police force. The murders are reminiscent of another string of serial murders that occurred six years ago prior to the game where Reiji lost his fiancée, which drives him with a strong desire to solve this case. Later at a park, Reiji also meets a high school girl from Ouba Girls Academy named Touko Kuchiki, who asks him to find her real self. Reiji is initially unsure of what she means, but later finds out that Toko has an unusually complicated past that may have more to do with the current string of serial killings than Reiji initially expects. While working to solve the growing number of murder cases in Tokyo, Reiji takes some time out to get to know Toko and her friends as well as other students from her school while working behind-the-scenes to unravel the mysteries of her dark past.

• Reiji Tokisaka • Ryota Takeuchi (visual novel - full voice HD edition), Junichi Suwabe (OVA) • Reiji is the series' main protagonist and a private detective specializing in particularly brutal murder cases. Before the series of events, Reiji worked in the police force but then he was forced to quit after the death of his fiancée Yukiko; he lives with his younger sister Yukari (a student at Ouba Academy) who he cares for dearly and wants to make sure that nothing bad happens to her. He doesn't spend too much of his time at home due to his work unless he's off duty; he enjoys reading history books during his free time, even when he's in his office. He also becomes a substitute teacher teaching history at the same school that his sister attends. • Yukari Tokisaka • Kei Mizusawa • Yukari is Reiji's younger sister and a high school student at the all-girls Ouba Academy. An old-fashioned, reliable type of girl, she is very close to her older brother and often takes care of him even when he tends to be helpless when it comes to doing household chores and will usually become concerned and worried when her brother has to go out and solve certain cases. Like Reiji she is very academic, but she has strong interests in entomology (much to the dismay of some people including her brother) and has a huge collection of certain insects in her bedroom. She is a member of her school's art club. • Toko Kuchiki • Kei Maeda • Toko Kuchiki is a mysterious teenage girl who meets Reiji with a request that he help her find her "true self". Like Yukari, she attends Ouba Girls Academy along with being one of her classmates and also a member of the art club at her school; despite being one of the most popular students at school, she actually hides some secrets that no one else knows. She is shown to be a regular customer at Cafe Moon World, a restaurant/bar owned by Kyoko (a widow whose husband died long before the series events). • Toko Mizuhara • Mimi Yoshida • Toko Mizuhara is Kuchiki's best friend and classmate from school. Sharing the same name as each other (but spelled differently), the two girls are often shown spending time and hanging out together. Due to her poor background and having to live in a broken home, she is shown to have a severe inferiority complex, because of this she hates her parents, herself, as well as other people around her. Like most of the people from her school, she practically worships Kuchiki especially since she has been one of the few people that ignores her troubled background. Since her first encounter with Reiji during a school field trip, she holds a strong grudge against him fearing that he's trying to take her friend away. • Tsuzuriko "Tojiko" Yosomiya • Hinata Aoi • Tsuzuriko is an aspiring writer and one of Yukari's classmates/best friend from school who serves as a comic relief in both the OVA and visual novel.

She is often referred to as "Tojiko" by Reiji claiming that her real name is hard to pronounce, much to her dismay. • Orihime Tsukishima • Rino Kawashima (visual novel) • Orihime is the president of the student council at Ouba Academy. A talented honor student, she comes from a wealthy, loving, and influential family; her charisma makes her an idol of many of her classmates. • Uozumi Kyouzou • Jun Ozaki • Reiji's best friend and former colleague from the police, Kyozo and Reiji have known each other since they were students at the police academy where they both joined the force and worked under the same supervisor. Even after his friend resigned from the police force, he still relies on Reiji's help in solving cases. He is also a regular customer at Cafe Moon World and has a crush on the owner, Kyouko. • Hazuki Kyouko • Shiho Kawaragi • The widowed owner of Cafe Moon World and a close acquaintance of Reiji and Uozumi (two of her regular customers), Kyoko is one of the few people who remembers Reiji's dark tragic past and she was also an old friend of his deceased fiancée. Since they have both lost someone important and special to them, they are able to connect on a more different level. Her cafe has a lot of regulars including Uozumi and Toko Kuchiki. • Hatsune Amemiya • Himeno Miyabi • Hatsune is a waitress working at Cafe Moon World who used to help out at a brothel entitled Yukishiro, but after the establishment was shut down, Madam Ujaku took Hatsune under her wing and gave her the name Amemiya. She learned how to write from Shugo when they both lived at the Yukishiro brothel, so she gets mad whenever people say bad things about him. • Shinji Mamiya • Daisuke Yagami • Shinji, also known by his pen name Shin Katsuragi or Katsuragi-sensei for short, is one of the series' main antagonists.

He often advises Reiji that the school rules do not allow for much interaction between siblings, but he does appear to sympathize with Reiji as he struggles to deal with the seemingly emotionless students who lack any trace of individuality. • Marisu Sutera • Yuzuki Akishiro • Maris is a half-Japanese friend of Reiji's who works as a tour guide at the art museum that Reiji and the students visit during a school field trip. • Mio Mizuhara • Kei Kusamura • Yorutsuki Mori • Jin Munakata • Naoki Murase • Daichi Hirono • Tokio Saeki • Kouta Umanami • The vice principal of Ouba Girls Academy as well as the faculty advisor to the art club, he hires Reiji to search for the missing students at his school and pleads with him to investigate school grounds to prevent any more casualties. • Tamaki Saito • Tomoaki Ikeda • A psychiatrist at the hospital owned by the Kuchiki family. • Satou Ayumu • Shiho Kawaragi • Yui's best friend and classmate, she runs into Yukari and the rest of the art club members a lot. She became rather depressed after her friend's disappearance, and as a result, doesn't talk to others as much as she used to. • Natsume Takashiro • Ryoko Tanaka • Takashiro is a coroner who forbids anyone to address her as anything but "Natsume-san". Though she can be rather shady with her words and actions, her skill as a coroner is undisputed.
