Friends

 * Kiriyama Yui: A friend and classmate of Yukina's. The two typically spend their lunch break eating and chatting together. Yukina became upset with Yui for not having the determination to go on a date. She decides to help plan a date for Yui and subsequently spies on said date. Yukina views Yui as a sisterly figure, occasionally referring to her as Onee-san, "big sister."
 * Nagase Iori: A friend and classmate of Yukina's. The two decided to spy on the couples to help them on their relationships. Iori also frequently stops Yukina from saying perverted things.
 * Nakayama Mariko: A friend and classmate of Yukina's. She helped Mariko on her first date and, like with Yui, was upset that Mariko had never been a date before.
 * Yaegashi Taichi: A classmate and friend of Yukina's. Like the other girls, Yukina enjoys ganging up on Taichi and teasing him during breaks, especially about Inaba. Yukina mistakingly thought that Taichi and Inaba's relationship is a bit too close that they did something together.
 * Oosawa Misaki: Yukina's best friend and Track & Field teammate. The two are shown to be good friends and they helped each during the Personality Exchange phenomenon. After Misaki lost her memories about the club and the phenomenon, Yukina became depressed when her attempts to reconnect with Misaki end in failure.
