Seventeen-year-old Tenchi Masaki grew up hearing stories about how his ancestor used a sword to seal a demon inside a cave seven hundred years ago. When curiosity gets the better of him, Tenchi goes to the cave and stumbles across the sword from the legend. Thinking that the story is nothing more than a fairy tale, he removes the blade and inadvertently releases the demon, who turns out to be a space pirate named Ryouko Hakubi. Furious about being trapped for so long, she attacks Tenchi, but he is able to repel her with the sword, awakening his inner power. After seeing this, Ryouko takes an interest in her unlikely savior and decides to crash at his place. As if it were a chain reaction, more alien women—Aeka Jurai Masaki, an uptight princess from the planet Jurai; Sasami, Aeka's sweet younger sister; Mihoshi Kuramitsu, a ditzy Galactic Police Officer; and Washuu Hakubi, a wisecracking genius—gradually come in contact with Tenchi and begin living with him. Through his encounters with these five women, Tenchi begins to learn more about his ancestry, newfound power, and the looming threat lurking beyond the skies. [Written by MAL Rewrite]

Nobita requests of Doraemon the Moshimo-box and wishes for the world to become a place where the use of magic is possible. Witchcraft replaces science and technology and everyone makes use of it on their daily lives, except for Nobita, who, like usual, isn't very good at conjuring spells. Frustrated, he plans on returning things to their past state, but his mother threw the Moshimo-box away. One day, Doraemon and his friends meet Professor Mangetsu, who studies magic and magical beings such as goblins, and his daughter Miyoko, and are warned of the dangerous approximation of the "star of the Underworld" to the Earth's orbit. With the future of the planet at stake, the group must travel to the Underworld and pierce the heart of the Underworld King with a silver dart, as detailed in the ancient texts of "The Chronicles of the Underworld". Their attempts are, however, thwarted and Miyoko captured. Doraemon and his friends then decided to use the Time Machine to return to the past and, using Dorami's Moshimo-box, they manage to restore the Earth. The events on the Underworld continue, however, to take place in a Parallel Universe, where Miyoko is still captive. As a result, the group is once again forced to travel to the Underworld and defeat its tyrannical ruler once and for all. (Source: AniDB)
