Kris Dreemurr is the adopted human child of the Dreemurr family in Hometown, consisting of Asgore, Toriel, and Asriel. They're the only human in town, and they stand out a lot. That hasn't stopped them from gaining friends, of course, such as their childhood friend, Noelle Holiday, as well as recently a tall, tough, and mean-looking monster named Susie.

Kris's voice (going off of the most common approach to it with examples like Revtrosity's or Man On The Internet's interpretation [search for the Sanctuary With Lyrics video to see what I mean]) is more deep and masculine mixed with a bit of femininity.
