Haruki is a shiny young pup born to Kumo's second litter alongside his sister. He is Kumo's third son born, and he closely resembles his father in appearance. He earned the nickname of "River" in the pack thanks to his bright blue fur and cream undersides. Almost like a sandy river bank with water splashing ashore. Haruki doesn't get much attention from his mother. In fact, Asuki, his sister, steals of Kumo's love. This has made Haruki a bit jealous and somewhat possessive of things that are his, as he believes others will try to take them away from him.
