Kavchi

Kavchi is the slash ship between Kaveh and Tartaglia from the Genshin Impact fandom.

Canon
Kaveh and Tartaglia have yet to meet in canon.

Their models are the same, which means that their heights generally align. They both have bangs that swoop in opposite directions from each other. Their outfits both feature a red around their shoulders (Kaveh's cape and Childe's scarf), a greyscale top, and a hair accessory on the left sides of their heads. Their tops both have triangular windows that show some skin. They both have light colored hair. They both wear their visions around their waists.

Kaveh is described in canon as something prone to overthinking things, while Childe is prone to shortsightedness. While they are polar opposites in this way, the two of them share a hidden "dark side" arisen due to their respective pasts. Kaveh is described as melancholic under his cheerful façade, while Childe's appearance belies his bloodthirsty nature.

Fanon
While Kaveh and Childe have never met in canon, there is some basis for their potential as a pair. For instance, Kaveh's motivations in life primarily revolve around creation and altruism, while Childe's pertain to destruction and death. This plays into the popular "Opposites Attract" trope.

Moreover, the two are complementary in several regards. It can also be surmised that Childe's hedonistic but reckless behavior and Kaveh's high-strung but dutiful attitude could serve to balance each other out. Additionally, Kaveh struggles with poverty while Childe has never been shown to hesitate when it comes to extending financial support. Kaveh is self-sacrificing, reluctant to accept charity due to his unresolved feelings of guilt, and often exploited as a result. Childe is straightforward and non-transactional, which could provide a positive counterpoint in Kaveh’s life. One could also make a point to analogize Kaveh’s appreciation of beauty and Childe’s thrill seeking as congruous manifestations of passion for worldly pleasures.
