Himeka Saiki (才さい奇き 姫ひめ歌か, Saiki Himeka?) is a character in The 100 Girlfriends Who Really, Really, Really, Really, Really Love You. She is Rentarou's 26th girlfriend, and a third-year student at Ohananomitsu High School, in class 1-6. Himeka also performs as a soloist and singer, under the stage name Kiki (奇キ姫キ, Kiki?). She is also known by the epithet The Songstress Prodigy (若わかき 天てん才さい 歌うた姫ひめ, Wakaki tensai utahime?). Himeka is a musical prodigy, and is popular among those her age. However, she has a desire to be seen as abnormal, believing that abnormal geniuses are much cooler and stand out more. As such, she exhibits some abnormal behaviors (such as using her chopsticks upside down, or wearing mismatched shoes) to be seen as abnormal - although these deeds are so minor, her fans and supporting staff just see her as a little clumsy instead. Himeka initially rejects Rentarou due to perceiving him as "normal", she changes her mind after learning he already has 25 girlfriends at the time. Kurumi Haraga is a big fan of Himeka.
