Kazuyaka

Kazuyaka is the Het ship between Kamisato Ayaka and Kaedehara Kazuha from the Game Series Genshin Impact

Canon
While there currently are no canon interactions of Kazuha and Ayaka in the game, they share quite a lot of similarities. Kazuha helped the resistance, even being the one to block an attack made by the Shogun, and Ayaka secretly helped the Traveler withstand the Shogun. Kazuha and Ayaka also both have the same animation of sheathing their sword. Cryo and Anemo also cause the elemental reaction “swirl”. Both characters are known to be some of the most powerful in the game. Ayaka has an alternative sprint, which helps travel around and makes ice-bridging more convenient, and Kazuha can boost you up in the air and reduce 20% stamina consumption while sprinting. It is notable that both are helpful for travelling.

Fanon
Kazuyaka is not one of the most popular ships, but many fanart and fanfics of Kazuyaka have been made.
