Xiaoyu

Xianyu is the het ship between Xiao and Ganyu from the Genshin Impact fandom.

Canon
Xiao and Ganyu are both Adepti and Immortal. They do not really interact a lot in the canon timeline but they still interacted to each others.

Sinae Unicornis
In Ganyu's Story Quest, after finishing Cloud Retainer's trial. Ganyu then went to the next trial which is Xiao's trial, Xiao tells Ganyu that she was half an hour late. Ganyu then tries to explain why she was half an hour late but Xiao said that he doesn't need Ganyu's explanations and doesn't require any mutual understanding between them, Xiao then says he is just helping Ganyu with her training.

Quotes
"Ganyu is neither mortal nor illuminated beast. Wandering both the mortal and Adepti realms with duty as her sole guide, it was inevitable that she would become perplexed... What? Me? You believe a Yaksha who knows nothing more than how to massacre countless souls and emerge unscathed is a suitable mentor for such an individual? ...Your mind occupies a very different world from that which your body inhabits."

- Xiao's Voiceline about Ganyu

"He seems like a bit of an outsider, socially. Probably just his personality... I can understand that, to be honest, but I'm not really about to try and get close to him. I mean... all the people he's ever agreed to team up with are no longer with us..."

- Ganyu's Voiceline about Xiao

Fanon
