TsukiHina

TsukkiHina is the slash ship between Tsukishima Kei and Hinata Shouyou from the Haikyu!! fandom.

Canon
Tsukishima and Hinata are both first year middle blockers in the Karasuno High School Volleyball Club. They first met when they joined the said club, and have kept a sort of rivalry relationship ever since.

Tsukishima often picks on Hinata for his height, actions or way too active personality. When they first encountered each other, Hinata expressed how much passion he had for volleyball, which annoyed Tsukishima at that point in time as he still had his mindset of the team just being a club and nothing more.

Over the course of the series, they learn to respect one another and even work together as they are both regular players on the court.

They are also supposed to represent the direct contrast of each other. Tsukishima is supposed to represent the moon, calm, intelligent, collected and rather not in the spotlight, while Hinata represents the sun, active, joyful, passionate and attention arousing.

Fanon
TsukkiHina is a rather known rare pair.

The fans like to keep to the contrast of moon and sun in many pieces of art and writing. A lot of fanfictions also involve Yamaguchi having unrequired feelings for Tsukishima, sometimes being a past relationship of Tsukishima or even being a rival for Hinata. The same counts for Kageyama having feelings for Hinata.
