Kaeya Alberich is an outwardly confident and charming neko with a flair for drama. He is sometimes seen as overly laid-back and even lazy, but he is always serious when the situation calls for it.  His determination and resilience  have allowed him to survive the streets of Mondstadt after he was kicked out by his adoptive brother Diluc - in result of their father Crepus' death. He often puts himself in stressful situations to test both his own and other peoples' values.
