Albedo

Albedo is described as a kind and popular figure in Mondstadt, as well as an alchemical genius. He pursues the "truth" of the world of Teyvat as per his teacher's request and seems to be able to create living organisms through his alchemical talents. Albedo is also good with children, as he gets along well with Klee, who considers him kind and patient, while he in turn sees her as a sort of younger sister.

Like Sucrose, Albedo spends most of his time as a recluse who shows a slight distaste for speaking to others due to the trouble required to maintain social rapport; he does not stutter like his assistant.

Albedo is a talented artist, who took up the hobby initially to help with his experiments, but now does it to relax. He serves as Xingchiu's illustrator, considering him to be a good author. He researches and studies anything that interests him, stating that he enjoys the feeling of enlightenment in doing so. Once this feeling wears off, he quickly abandons what he was doing as the truth feels bittersweet to him. He retains this outlook when it comes to eating, preferring light and sweet dishes.

Despite being viewed positively by the people of Mondstadt, they know almost nothing about him, and he is secretive about his past. He is implied to be a homunculus created by his master, as he curiously sees her as his creator, has no memory of his family, and considers himself to be of a different "substance" compared to the people of Teyvat. Due to the ancient and forgotten knowledge he possesses, he even considers himself a threat, with Venti and Dainsleif considering him dangerous for that reason.
