It's the same story as the original Anime and Manga. Ataru constantly hits on girls even though Shinobu is his girlfriend. They frequently beat him up. Ataru is randomly selected by a computer to save the world. He must play a game of tag with Princess Lum and grab her by the horns. If he fails the alien Onis will take over the world. Shinobu says she will marry Ataru if he wins. He catches her and says "I'm gonna marry her." Lum thinks Ataru is talking about her and thinks she is married to him. When he tries to hit on other girls Lum uses her powers to electrocute him. They always go on crazy adventures together. The Art in the reboot is gorgeous. It's a mix of the original 80's style and a more modern art style. They try to introduce all the characters from the manga as fast as possible. The original 80's anime took longer to introduce the characters. Unfortunately the violence is slightly toned down. They sometimes use freeze frames but it's still funny.
