Diluc has pale skin, red eyes, and bright red hair that goes down to the middle of his back. Despite coming off as bitter and grumpy through his speech, he has a gentle, tender, and modest nature. Kaeya is confident and charming with a flair for drama. He struggles with loneliness but he playfully deflects when confronted about it. He's tan, has navy-blue hair. His visible eye is periwinkle with a diamond-shaped pupil. Right eye covered by an eyepatch. More flirty.
