Seems cold and firstly very distant, but very friendly and polite. He knows etiquette very well. Not really good at showing emotions, but very good with words and gives good advices. His parents died and he has a bad relationship with his step-brother, Kaeya, based on their past, and he doesn't know how to solve their problems between them. He carries a lot of pain in his heart, but he doesn't really talk about it, only if he's close enough to someone.
