KiyoYachi

KiyoYachi is the femslash ship between Yachi Hitoka and Kiyoko Shimizu from the Haikyu!! fandom.

​Canon
Kiyoko is a third year student at the Karasuno High School, as well as the official manager of the Karasuno Boys Volleyball Club. Yachi is a first year and also became a manager for the Volleyball Club after Kiyoko asked her to. She'll be taking Kiyoko's place when she leaves after graduation.

Yachi has admitted (in her mind) that she finds Shimizu very attractive. Yachi blushes very often if she sees Kiyoko and thinks if she walks next to her assassins would comes to kill her because she also thinks Kiyoko is the most popular girl in the school. Kiyoko has also blushed sometimes because of Yachi.

They have become good friends and are usually seen together. Kiyoko has become more open in the club due to Yachi being another female
