Kaeya is an outwardly confident and charming individual with a flair for drama. He is sometimes seen as overly laid-back and even lazy, but he takes his work seriously. He is surprisingly popular among the seniors of schoo, even earning himself the title of "top candidate for grandson-in-law." His charisma and determination have earned him the admiration, respect, and favor of many people in school — yet, his love for provoking others has also gained him the exasperation of those people.
