Kaeya, like his adopted brother, is shrouded in mystery. Despite his popularity, barely anyone knows anything about him. But due to his charming, flirtatious and teaseful and compassionate demeanor, he continues to be one of the most well-liked people, particularly among the elder. Despite the fact that some may consider him to be lazy, he is normally willing to resort to more extreme and ruthless measures than the rest of the Knights. He seems to have a façade put up with the general public.
