An original "character" created by Poco. An mysterious, undying living creature, Kuroino is frequently seen with, and nearly as often abused by, Shiratama Kitsune, though it is by no means exempt from this treatment from the others. It mysteriously revives each time, however, be it from being smashed by a steamroller to be used as an umbrella, to being eaten by a giant fish, to being cooked by Tsutsune.
