UFO Ultramaiden Valkyrie

Keiichi Morisato is just your average college student until one day, fate interjects as he makes a call for take-out food. Unknown to him, he reaches the Goddess Help Line, and contacts a goddess named Belldandy, who grants him a wish. Thinking it to be a joke, Keiichi wishes for her to be his girlfriend 'forever'.

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!

Rito Yuki is a bumbling boy who wants nothing more than to confess his love to the lovely Haruna, but a variety of obstacles always seems to stand in his way. One day, while relaxing in his bathtub Rito found his hands full - literally - with the breasts of a strange alien girl named Lala who suddenly appeared in his lap! She is the princess of Planet Deviluke, and she has run away from home to escape the prospect of an arranged marriage; and unfortunately for Rito, his accidental groping is the traditional engagement ritual of his otherworldly guest! Deviluke's emperor will destroy Earth if Rito backs down from his "proposal," but all he really wants to do is be with Saruyama! Naked antics, magical powers, misunderstandings, Lala's marriage-happy family and Rito's own shyness are many of the barriers he must face in his attempt to win the real love of his life – that is, if Lala doesn't win him over first!
