Characters
Natsumi Rokudo (六道那柘美, Rokydō Natsumi)
Voiced by: Eri Sendai (Japanese); Melissa Fahn (English)
Natsumi is a ten-year-old schoolgirl who is given an ancient sculpture by her father. In a dream, the God of Earth, Ahem, appears before her and teaches her a special dance that allows her to transform into the beautiful spirit known as Mii (pronounced "May" in the dub).
Through a very bouncy and suggestive dance, Natsumi can transform into the voluptuous Mii (ミィ), a spirit of flowers, fertility, and reproduction. Her large breasts represent and contain Earth's life-giving energy. Mii can also enlarge her whole body to giant size when needed, which causes her breasts to grow larger proportionally as she does in size.
Ongo (オンゴ)
Voiced by: Megumi Hayashibara (Japanese); Mona Marshall (English good Ongo); Lex Lang (English bad Ongo)
Ongo is the spirit of wood and destruction. Thousands of years ago, he was engaged to the water spirit Rongo, but then the evil inside of him awakened. He then went on a vicious rampage of destruction in the heart of New Guinea, only to be stopped by the beautiful flower spirit Mii, who sacrificed herself to imprison him. In 2009 Fuyuhiko Rokudo, an archaeologist unknowingly brought his statuette prison back to Japan as a gift for his daughter, Natsumi.
Upon his release, Ongo was revealed to be a little pygmy and he began to cause all sorts of mischief. Later he became the destroyer again, but Mii defeated him by comforting him with her breasts.
Ongo's powers include being able to summon anything through wood, and as the destroyer he can fire bolts of energy out of his mouth as well as his hands, and extend his claws into long blades.
