UFO Ultramaiden Valkyrie

In the present, the Japanese government has been conducting experiments to genetically engineer a human: a girl named Rizel. The experiment was a success -- sort of. While healthy and cheerful, 12-year-old Rizel also ended up possessing the uncanny need for “love” to further her development, as well as tears which were in fact volitile explosives! When sadness can end up destroying a city block, what's a girl to do except... get married?! For Iwari Tomori, the young man chosen as the most appropriate partner for Rizel, life is about to change, for better or for worse!
