Shiro and Kuro are old characters I recently overhauled and felt like colouring, but as I did I disliked their names. They just don't suit them anymore. So I'm keeping the feel, but changing their names. Yuki means snow and that's white so Shiro the mutt is now Yuki. Kuro used to be a black tuxedo cat thing, but now...well....he's still a cat thing? I kept thinking Kiro instead of Kuro in my head too so that's club cat's new name. New name to go with his new look. I think their personalities are still pretty much the same. Yuki for sure.
