A running gag in Bleach, mainly in the omake chapters, is Soifon's obsession and admiration for Yoruichi Shihouin, the former leader of the special forces, which borderlines on romantic feelings. She also seems to like anything that resembles a black cat, which is Yoruichi's preferred form. This is also evidenced in the Shinigami Illustrated Picture Book (comedic skits at the end of an episode) segment in episode 97, where Rangiku Matsumoto gives her a "Yoruichi" (black cat) stuffed toy as a present from the human world. During the animation of the 7th ending theme she is holding her tenderly. Soifon also tries to give a heart-shaped box of chocolate to Yoruichi in one of the omake chapters that aired on Valentine's Day, but fails to when Yoruichi switches to her feline form. In a VJump omake chapter, the Gotei 13 were asked to give ideas to the Commander-General for a shinigami video game. Soifon suggested a game with herself and Yoruichi as the main characters. In another VJump omake chapter, the Shinigami's Woman Association presents the idea of shinigami cellphones. Soifon suggests one that has a direct single line to Yoruichi so she can "talk to Yoruichi-sama as much as she wants." In yet another Vjump omake chapter, the Shinigami's Woman Association, she and Kotetsu "peeped" on a naked Yoruichi while the lady was taking a bath on the springs in order to take pictures of her for the association's calendar. During her momentary visit in the real world, at Kisuke Urahara's shop, she expresses dismay at Yoruichi's living conditions since leaving Soul Society and comments to Urahara that if anything happens to Yoruichi she will make him pay. Recently, the Shinigami Illustrated Picture Book for episode 117 shows Soifon fawning over pictures of Yoruichi - even one where she's eating like a glutton. Also, during the credits for the OAV "The Sealed Sword Frenzy", after Yoruichi walks away with Urahara, seeming as if they were on a date, she is seen staring at the couple, her hand in a fist and her face irritated.
