A stranded earthling, a sarcastic robot, and a fairy trapped on a planet ruled by a false god sounds like Saturday morning cartoon setup. The OVA demolishes that promise in its final minutes. What starts as campy sci-fi comedy becomes something genuinely unsettling about blind faith, corporate manipulation wearing divine robes, and how easily people mistake authority for truth. The animation is rough enough that it almost feels like you're watching something you shouldn't, some artifact from a stranger's dream. By the time Gavana's true nature reveals itself, you realize the whole story was a con, and so were you. It's a single episode that swings for something much larger than its budget allows.

After their spacecraft fails, the Earthling Ryu and his AI robot companion MOS crash-land on a mysterious planet called Gdleen. There Ryu meets Fana, a cute Euradonian fairy. The planet is caught up in a long-running dispute over a temple, and Gavana, a being who claims to be a god, captures Fana to offer her as a sacrifice. Ryu sets out to save her, and two questions hang over the adventure: whether they can all escape, and who or what Gavana really is. Science fiction and fantasy meet in this single-episode OVA from 1990.
