=== Older Brother Kidnapping Case (Manga: [[Volume 18|176-178]], Anime: [[Episode 129|129]]) === [[File:129-1.png|thumb|left|200px|First Haibara's "evil" appearance.]] Conan's class receives a new student named Ai Haibara. She acts rather cold and reserved when the Detective Boys try to befriend her, and Genta notices she's looking at Conan suspiciously. She tells them where she lives but Conan fails to realize it's at Agasa's home (Tokyo blocks are not numbered in sequential order and Conan has never had reason to learn Agasa's mailing address due to their being neighbors). After school, a boy named Toshiya asks the Detective Boys to find his missing brother. The Detective Boys along with Haibara investigate Toshiya's house and finds a painting of [[Wikipedia: Natsume Sōseki|Natsume Sōseki]]. Toshiya reveals that before his brother disappeared, a woman, who had an interest in that portrait, approached Toshiya's brother. The Detective Boys search around town to ask whether anyone has seen the woman or Toshiya's brother. Conan notices that a man was using a counterfeit ¥1000 and realizes Toshiya's brother was actually kidnapped and forced to help create counterfeit bills. After following the man along with the clues Toshiya's brother left behind, they are able to apprehend the organized crime group and save Toshiya's brother.
