DaiYui

DaiYui is the het ship between Daichi Sawamura and Yui Michimiya from the Haikyu!! fandom.

Canon
For the majority of the series, both Michimiya and Sawamura are third-years at Karasuno. They are both captains of the girl's and boy's volleyball teams. They are childhood friends and it is shown in some episodes that Michimiya takes Sawamura's words of wisdom to her very seriously and uses them to grow.

Michimiya and Sawamura went to Izumitate Middle school together. They became good friends and occasionally practiced volleyball together.

Their first interaction in the anime is in the 5th episode of Season 1. She asks him about Karasuno's match with Seijoh the following day, and if he was nervous. He tells her about the new first years, and how he believes that if they prove effective they can win. Michimiya blushes a little.

We see them again in the 14th episode of Season 1, "Formidable Opponents." Michimiya accidentally expresses her concern that the girl's volleyball team will lose again. Sawamura tells her to believe in herself, saying that "No matter how formidable and unbeatable, you'll never win if you don't believe you can." She remembers how he said the same thing to her back in middle school and quotes him, blushing. Despite this, she takes these words to heart and uses them to inspire her team to work as hard as they can during their Interhigh match in the following episode.

In the 1st episode of Season 3, "Greetings," Michimiya gives Sawamura a good-luck charm, though she states that "It's not just for you, personally." Daichi thanks her and leaves, and afterwards Michimiya hugs her friend, flustered, who retorts "I'm surprised you were even able to give it to him."

Michimiya seems to get nervous and flustered around Sawamura, often being clumsy, repeating words and struggles to find the right words to talk.

Fanon
