There is a galaxy called Iris 160 million light years away from our Milky Way, and in this Iris galaxy there is a charming rainbow-colored planet. This rainbow-colored planet also has many countries like ours, but the people living on this rainbow-colored planet are different from the people on our earth. Because some of them have cat ears, some have mouse tails on their backs, and some have a pair of beautiful snow-white wings on their backs.
