Kaeya covers one of his eyes with an eyepatch. In fact, he said he inherited it from his grandfather (who he says was a pirate). On top of that, Kaeya has dark-tannish skin. An accomplished swordsman. Kaeya is an outwardly confident and charming. Diluc to be faithful in his duties. After his father's death, he has been suppressing himself. Despite coming off as bitter and grumpy through his speech, he has a gentle, tender, and modest nature.
