Diluc Ragnvindr was a tall young man, aged twenty-two, with an athletic build and light skin. He had fiery red eyes and a handsome face. His long wavy hair, which was the same color as his eyes, was tied messily into a ponytail that flowed down to his lower back. Despite being the owner of Mondstadt's largest wine industry, Diluc is not fond of alcohol. Despite coming off as bitter and grumpy through his speech, he has a gentle, tender, and modest nature.
