SemiShira

SemiShira is the slash ship between Semi Eita and Shirabu Kenjirō from the Haikyu!! fandom.

Canon
Semi Eita is a third year while Shirabu Kenjirō is a second year at Shiratorizawa Academy. They are both on their school's volleyball team, both playing the same position of setter. Naturally, this would spark a rivalry between the two as there can only be one starting setter on a team. Despite Semi getting into Shiratorizawa with a sports scholarship and Shirabu from the standard entrance exam, Shirabu manages to upstage his upperclassmen, taking the starting setter position for himself while leaving Semi as the pinch server.

However, it is shown that Semi does not hold a grudge against Shirabu in terms of the team's starters and is rather understanding on why his underclassman got the spot instead of him. Though, this does not stop Semi's dislike for Shirabu's dismissive and uninterested behavior, especially when he tries to give setting advice as seen in Shiratorizawa's match against Karasuno (as he calls Shirabu "a little brat" after he flatly ignores Semi's given advice).

Fanon
In most fanworks of this pairing, Shirabu and Semi are both portrayed to be more aggressive, snarky, and salty characters. This leads to the fanon pairing having more of a popular rivals to lovers sort of dynamic, with plenty of lighthearted banter and teasing remarks being thrown between the two. Along with both parties having a hot-headed personality, SemiShira is shown as a more passionate ship with the two often butting heads and having petty little arguments.

Most of the time, this pairing in fics is often attached with the mutual pining tag, with Shirabu being shown to be a bit of a tsundere in contrast to Semi's fanon caring nature. Overall, SemiShira is shown as a cute relationship with confessions and pining scenes being written as nothing short of an absolute, tension-filled disaster.

Despite both character not having the most amount of screen time (both together and not), SemiShira is a decently popular ship with the two usually written as a smaller side-pairing, usually with more popular ships such as UshiTen (Ushijima Wakatoshi & Tendo Satori) or in text-chat AU's in fanfiction.

Trivia

 * With the opt:true fliter applied, SemiShira is boiled down to having only 378 tagged fics on AO3 (as of March 21st 2021).
 * In the manga after the timeskip, Semi appears to still have Shirabu's number saved on his phone when he texted him about his attendance to the Alders .vs. Black Jackals game, implying they still kept in contact despite their rocky relationship in high school.
 * The contact photo saved is a chibi of a grumpy Shirabu's head.
