DARTS

A bunny alien, a maid-dominatrix, a cyborg, a magical girl, and a transforming super hero set out to vanquish a set of monsters to retrieve a set of magical Mahjong tiles known as the Pai - these ancient artifacts will grant the one who gathers them a wish, and these girls aren't going to let anything stand in their way - monsters, or each other!

Fleeing from his own race, Orgun—an alien being with superhuman abilities and unearthly weapons—travels to Earth to find an answer to his origin. There, he bonds with a young man named Tomoru to defend Earth against the Evoluders, who seek nothing but destruction of other civilizations.
