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 color palettes both feature a red accessory (Kaveh's cape and Childe's scarf) and a greyscale top.

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 facade, while Childe's appearance belies his bloodhirsty 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, 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.
