EiMikoSara

EiMikoSara is the Poly ship between Kujou Sara, Raiden Ei and Yae Miko from the Genshin Impact fandom.

Canon
Ei, Miko, and Sara each have a voice line about each other. Along with that, they have all interacted at least once separately. Their color schemes are also very similar, as Ei and Sara have purple hair, and Miko has pink hair, which is very similar to Purple. Each have a different relationship with each other. Yae and Sara are practically enemies, Ei is Sara's ruler (Sara also being her loyal-general), and lastly, Yae and Ei get along very well.

The three have a couple of similarities. They're all from Inazuma, all have an electro vision, and have similar personalities.

Fanon
This ship isn't very popular in the Genshin Fandom, however, is shipped for many reasons. While it's not too popular, It is most definitely, Ei, Sara, and Miko's most popular poly ship on AO3 and anywhere else. Speaking of which, it currently has 95 works on AO3. A reason for these three being shipped is because some EiMiko and EiSara shippers can't decide on either ship, and so decide to combine the two. EiMiko, EiSara, and YaeSara are each popular on AO3, with over 100 works. EiSara has 1997 works, YaeSara has 220, and EiSara, has 388.
