All his life, Shiki has been surrounded by machines. At Granbell Kingdom, a long-abandoned amusement park, he is the only one of his kind around. That is, until Rebecca Bluegarden and her feline companion Happy arrive, unaware that they are Granbells first visitors in one hundred years. Their goal is to make fun videos for their B-Cube channel, but what they find instead is a friend in the socially awkward Shiki.
