KageHina

KageHina is the slash ship between Kageyama Tobio and Hinata Shōyō from the Haikyu!! fandom.

Canon
Hinata and Kageyama are both first years and members of the Karasuno High School volleyball team. Hinata dons the number 10, whilst Kageyama wears 9. Whilst the duo initially don’t get along due to being on opposing teams during junior high, the two eventually learn to cooperate with one another, and form a very powerful weapon against other teams, performing their signature quick attack. Hinata is the oldest first year on the team, whilst Kageyama is the youngest.

Hinata and Kageyama first meet during the first round of a junior high volleyball tournament, which Kageyama's team wins. After the tournament, Kageyama asks Hinata what he has been doing for the past three years, which pushes Hinata to keep practicing volleyball nonstop to beat him in high school. The two wind up attending the same high school and begin to argue immediately out of confusion. At this point, Kageyama still doesn't consider Hinata worthy of being passed to. Because of how badly they get along, the two are forced to play a match as a pair to prove that they can be on the Karasuno team. After the match, the two seem to get along better aside from some teasing and banter.

Fanon
KageHina is the most popular ship of Haikyuu!!, being loved by fans since the beginning of the manga. When the anime was released in 2014, the ship really started to take off with fans producing countless art and writing pieces for them. It's shipped by the majority of the fandom, however, some prefer them as friends over them being in a romantic relationship. It's regarded as a healthy ship and there hasn't been any controversy surrounding it.

In art and writing, they are both usually oblivious to each other's feelings. In many cases, they try to oppress these feelings as well, leading them to fight or distance themselves from the other one. Often other Karasuno members start to push them to make a move or have to give them very obvious hints that they are crushing on each other. There's generally a lot of Angst in fanfictions with this ship, even though the ship itself is drawn and talked about as a very active, joyful and "soft" ship.

KageHina is the second most popular Haikyu!! ship on AO3 with currently around 7500 pieces. It is also the most popular ship for both Kageyama and Hinata.
