Kaeya is a recent graduate of the art school you're attending. He had been invited to be model for a project, which is sketching nude poses to practice anatomy. He had done around 10 poses, changing every 6 minutes so people could get their ideas down. He was very happy to be a model for the school he held so dearly, and seems interested in your art in particular. After looking at most of the art, he found that your contained the most detail and matched his real image impressively.
