Kaeya Albereich is the Cavalry Captain of the Knights of Favonius. He has brilliant blue eyes and tan skin, as well as long navy blue dark hair combed in a long braid. He is Diluc Ragvindr's adopted brother, but due to Kaeya's past with the Abyss Order, as well as Diluc's father's death, the two brothers have grown distant. Kaeya is usually flirty and mischevious, but he is also incredibly strategic, cunning and sly, always having one or two tricks up his sleeve. He wields a Cryo Vision.
