Yami to Boushi to Hon no Tabibito

Gentle Himeko and reserved Chikane were born into very different backgrounds, but still became the best of friends. Their fates, they would soon come to discover, are intertwined in a fashion that they can't possibly imagine -- they are the reincarnations of two priestesses who once sealed the god of darkness Orochi in their past lives. Set to revive again, his giant robot-riding agents have set out to destroy the girls, one of whom is Himeko's friend who is in love with her. Riddled with memories of their past lives, the two try to survive long enough to cast the seal on Orochi again...

Imagine a mansion with a Christmas goods shop that appears out of nowhere, housing three beautiful sisters and a robot maid, all with very different personalities and figures. These sisters are looking for information that they can only acquire from "popotan," their term for dandelion flowers. After acquiring a hint of this information, the mansion and the girls vanish. Their travels take them through many places, and they meet a varied cast of characters during their quest, but what exactly is this information they're searching for so desperately?

Megami Paradise is an eden populated with scantily clad goddesses, protected by the outside world by a device known as the Astrostar. When the Mamamega, the protector of the Astrostar, requires a replacement, she contacts none other than Lilith, a bumbling girl who is destined to become a priestess and search for others to join her. But the Yamimama and her dark goddess followers have other plans for the Astrostar, and set out to take it for themselves! Can Lilith, Stasia, Juliana and the rest of the gang thwart these dark forces before it's too late?
