Tsukiuta: The Goddesses Who Came from the Moon

The Tsukiuta girls, more specifically Yuki, Reina, Matsuri, Kurisu, and Tsubaki were given the task to go down to earth for a special mission that they need to carry out. Are they up to the task they are given or hand over the task to another group? I apologize if the characters seem a bit OOC. *Monthly ships*
