The Boy's upbringing was similar to that of Goku from Dragonball. Once the people of his village found out about the boy, they burn Grandpa's home to the ground around them killing the old man. The boy escapes fire and laments grandpa's death. Later he finds a girl who can transform into a creature like he can. Later, another person comes in to complete the trio. One day he sees strange people with monster(or robot?) enforcers herding people from the village and when they hurt an old woman, the boy intervenes. He discovers later that they are doing genetic experiments to save their Alien race.
Among the aliens, there is political intrigue and friction between the scientist alien and his companions. There is also interest in the new human threat (the boy) since the earth was supposed to be weak and easy to conquer.
The anime's name was listed as "ONI" but I'm not sure if that was the real (or full) name. I'm also not sure if the anime was ever finished. I bought it as a VHS tape from a Comic-Con back in 1990 but it only had 4 or 6 episodes on it. The preview at the end of the tape said the next Episode was called: Iolite. The only other info I have is the ED got considerable play due to its dramatic slow, heavy Rock bass guitar chords at the beginning. (1-2, pause, 1-2, pause, 1-2, pause, da, da, da, da, da-dahh! repeat) I cannot find ANYTHING about this old anime on the web. The only references listed are either for the game Oni, the hentai OniAi, and to movies, games, and anime that came out recently. I need to finish this story if it exists, or at least hear the ed again. I hope you folks can help me. Thank you!
