In 19th-century London, class lines are sharply drawn, and the social standing to which people are born dictates the path their lives will follow. Emma, an honest and hardworking young maid, never felt her place in life to be a burden. But then she met William, a member of the gentry and the eldest son of a wealthy family. His warm smile and earnest affection threaten to capture her heart... but can love truly conquer all?

Kaoru is a college boy with everything going for him. He lives in a mansion with his beautiful fiancé, Aoi, all his roommates are babes, and they all have the hots for him. There’s just one hitch: due to family complications, Kaoru and his beloved have to keep their engagement a secret. As he gets tangled in countless steamy situations, can Kaoru overcome temptation and stay true to the lovely Aoi?

Lupika, an alien princess, is in love with a tofu seller. To make him love her too (at least, announce his love. He obviously fears the social taboo of a tofu vendor marrying a princess), she needs to get a love potion, which is in a certain temple. Legend has it that the only person that can obtain this love potion is the most lecherous man in the universe. That man turns out to be Ataru Moroboshi. Lupika kidnaps Ataru to make him get the potion, and Lum and her friends go out to search for Ataru.

It seems that Lum's grandfather made an agreement that should he have a daughter, she would be married to a traveling merchant that he met. Now, the merchant has come to collect due. Ataru is tricked into thinking that Lum wants to leave, and so, in a moment of anger, says he hates her. Arguments erupt, and Lum decides that she must know the truth of Atarus feelings. As for all the questions of importance for the Onis, a game of tag begins, one that Ataru can win simply by telling Lum I Love You. However, in the end his pride may end up dooming him. So begins the series of events that will at long last decide the future and fate of Ataru and Lum.

While performing in a student film, Ataru cuts down Tarozakura, a large, ancient cherry tree. Strange things begin to happen all across Tomobiki: a mountain appears out of nowhere, spring changes to winter, and Lum loses her powers, while those around her act as if she doesn't exist.

Ryoko throws a tea party for her friends. Flashbacks reveal the pasts of Ryoko's various guests.

The third film finds Ataru transformed into a pink hippopotamus, which sends Lum chasing after the wicked magician responsible, with catastrophic results. With Lum gone, her friends decide that there is no reason to remain, and so Tomobiki slowly returns to normal. The highlight of the film is a high speed chase scene with an angry Lum flying after the mysterious Ruu through the city at night and into a hall of mirrors (and illusion ). Ataru's true feelings for Lum are probably more obvious in this film than any of the others.

As the perpetually lecherous Ataru and his friends prepare for a carnival at Tomobiki High School, they gradually realize the days are literally repeating themselves. Any effort to break the pattern dumps them back where they started.

Cybot Robotchi, known in the United States as Robby the Rascal, is a 39-episode anime television series created by Ken Ishikawa and produced by Go Nagai's Dynamic Productions and the Knack animation studio. The series aired on TV Tokyo in Japan from October 1982 to June 1983. The series featured contributions from Tetsuro Amino as a storyboard artist and Masayuki Kojima as an episode director. A feature-length English-dubbed version comprising several episodes edited together into a movie, titled Robby the Rascal, was produced by Jim Terry's Kidpix Productions and released on home video in the United States in 1985. However, the English version deleted much of the risque humor that, while not uncommon in children's animation in Japan, would be considered unacceptable by American standards, with the policewoman Sachiko being the usual target of the fan service-oriented humor. The TV series also aired in its entirety in Italy under the title Robottino, and some episodes are also available in Spanish as Robotete.
