Haikyu!!

Haikyu!! is a sports manga series. It has been made into an anime and stage play.

Plot
Junior high school student Shōyō Hinata gains a sudden love of volleyball after seeing a national championship match on TV. Although short in stature, he becomes determined to follow in the footsteps of the championship's star player, nicknamed the "Little Giant", after seeing his plays. He creates a volleyball club and begins practicing by himself. Eventually 3 other members join the team by his last year of middle school, pushing Hinata to persuade his two friends who are in different clubs to join just for the tournament. However, they are defeated in their first tournament game after being challenged by the championship favorite team, which includes the so-called "King of the Court" Tobio Kageyama. Though Hinata's team suffers a miserable defeat, he vows to eventually surpass Kageyama and defeat him.

Fast-forward to high school, Hinata enters Karasuno High School with the hopes of joining their volleyball club. Unfortunately for him, the very person he swore to surpass appears before him as one of his new teammates. At first, Hinata and Kageyama are unable to work together, causing the team captain to kick them out of the club. The two decide to challenge the elder members of the team to a match, hoping that if they win they will prove they can work together and be allowed to rejoin. The team captain accepts the challenge, and working with another member of the team, Hinata and Kageyama win the match and are let back into the club.

By combining the genius-like qualities of Kageyama with Hinata's sheer athleticism, the duo create an invincible brand-new volleyball tactic. Their new combo allows them to get over their differences and creates a strange alliance between the two filled with fun and laughter for them and their teammates. Thus begins the Karasuno boys' volleyball team's journey to the top.

Fanon
The Haikyu!! fandom is very accepting of ships and ship wars (almost) never happen. Most ships are slash due to the anime focusing on mostly male characters. Most of the fandoms ship wars however focus around KuroTsuki, TsukkiYama and KuroKen.
