Kavethaynonari

Kavethaynonari is the poly ship between Kaveh, Alhaitham, Cyno and Tighnari from the Genshin Impact fandom.

Canon
All of the four characters know each other in canon, and have vastly different dynamics between each other. Cyno and Tighnari are close friends who often collaborate and work together, as is suggested by Matra's Encyclopedia of Plants description. Furthermore, they both take care of Collei. Kaveh and Alhaitham are roomates who, on the other hand, have a very tumultuous relationship, often bickering and riling each other up over the smallest things. Cyno and Alhaitham also have quite the antagonistic relationship, as their different philosophies often puts them in opposing sides. Kaveh and Tighnari, however, have an amiable relationship, and according to Cyno's voiceline "About: Kaveh" it seems that Tighnari finds the architect quite humourous. Cyno and Kaveh don't have any exclusive interactions, as well as Alhaitham and Tighnari.

The four are all incredibly intelligent people, as they have all graduated from Sumeru Akademiya while still being quite young. It's interesting to note how they all seem to have studied in different Darshans: Kaveh was a Kshahrewar student, Tighnari studied in Amurta, Alhaitham studied in Haravatat, and although Cyno's Darshan has not been confirmed, it's possible he may have been a Spantamad student since he and Lisa have studied under the same sage.

The four appear together for the first time in Alhaitham's Character Demo. Kaveh, Cyno, and Tighnari are seen at Puspa Café discussing about how strong Alhaitham really is. Once Alhaitham joins them, he tries to explain his point of view, but fails to be understood by the other three.

Fanon
Kavethaynonari is considered a rarepair within the Genshin fandom. However, Kavetham and Cynonari are considered the most popular out of them. Because of this, the fandom often jokes about the four going on double dates. Most people in the fandom believe Cyno and Tighnari would be romantic, while Kaveh and Alhaitham would be arguing the entire time. However, all four of them as a ship is often considered platonic.

After Alhaitham's Character Demo, a meme involving the four playing UNO has become popular on social media. In the video, Kaveh keeps fishing cards in hopes of finding a green card, with little success. Once he finally does, Alhaitham drops a card that changes the rotation, making it Kaveh's turn again, who unfortunately still doesn't have a green card.
