Akako Koizumi

Akako is a witch that practices black magic, including a spell which makes all men adore and love her, except for Kaito Kuroba, who she knows is Kaitou KID (yet he constantly denies it.) Hence, she wants to have Kaitou KID fall for her naturally, but never succeeds in doing so. Even though she has slightly evil intentions, she does care for Kaito in a way that could possibly be more than just to make him fall for her, as she's often tried to help him in her own little ways. Akako claims to have the spirit of Lucifer, and if she cries, she will lose her powers. Akako enrolls Ekoda High School, becoming a classmate of Kaito Kuroba and Aoko Nakamori. On Saint Valentine's Day, all the boys want chocolate from her, but Kaito: knowing that the only one in the world who can resist her is Kaitou Kid, Akako realizes that her classmate is the phantom thief. She then uses a voodoo to attract Kid and win his heart using magic, but she fails and the thief runs away. During a school trip to the mountains, after telling Aoko that she likes Kaito, Akako forces him to ski with her. She attaches a magic sticker on the boy's back, casting a spell by which (according to her) Kaito will fall in love with her, but she fails again and Kaito ends up skiing with Aoko. Akako then decides that she has to kill Kaito: after his death, it will be true that all men love her. She gives a cursed necklace to Ginzo Nakamori, but the inspector is unable to kill Kaitou Kid, who runs away. Akako waits for him on Touto Tower, but her feelings for Kaito prevents her from killing him. When Saguru Hakuba suspects that Kaito is Kid, Akako disguises herself as Kaitou KID to protect her friend's secret. Later on, she tries to use her magic to prevent the police and Shinichi Kudo from arresting Kid, but her butler stops her before using her powers publicly. Kaitou KID still manages to escape.
