very sweet and sensitive. is an alien from the same planet as kerrith and toraburu, but his entire family got banished when he was a baby, so he doesn't have much knowledge about what it was like there, and is just used to being on earth. he is kerrith's best friend on earth.

kerrith has a bit of a crush on umaru, and umaru can tell, but however, umaru is aro/ace and is not interested. he still tries to show a bit of affection to kerrith sometimes.

umaru loves to drink tea and pick flowers. he is really into plants. he has a cute lil garden in his backyard and wants to own a flower shop someday
