Anime based on a 1986 novel.

Despite being a refugee from an extinct planet, having an alcoholic as a father and an airhead for a mother, Maris' biggest problem is that she's a Thanatosian. Considering that Thanatosians are six times stronger than the average Earthling it shouldn't be such a curse, especially in a galaxy where violence is rife. But the accidental destruction she wreaks on everything she touches —even with the exotic alloy restraints she wears— means she's constantly in debt. Every mission she's assigned to by the Inter-Galactic Space Patrol becomes a cash-drain when all the damages are docked from her wage. But when she's selected to rescue the rich and sexy Kogane Maru it's like a dream come true. After setting him free from the terror of his ruthless kidnapper his eternal gratitude will surely guarantee marriage —and an end to all her financial headaches.

The story of the manga centers around Marimo Nogami, a usually quiet fourth-grade girl in elementary school. However, a certain incident leads to Marimo's personal strength blossoming.

After the battle with Doakuder at Soukaizan (the "other" world where the rainbow has disappeared because of the devils), a demon world Devil came to Genseikai (human world) and stole Wataru's conscience. Because of that, Wataru's heart of justice and his memories of being Kyuuseishu (world savior) vanished. After Shibaraku and Himiko brought him back to Shinbukai (the "other" world, where Soukaizan is located), Wataru regained his memories, however his conscience was still missing. To get it back, Kyuuseishu Wataru must return to fight the devils, rescuing all of Soukaizan from catastrophe!
