The cheerful Yuuki Cross and the gruff Zero Kiryuu are members of the disciplinary committee at Cross Academy, which houses two very distinct classes: the Day Class and the Night Class. Their job consists of upholding order between the classes when they switch out. While that may not seem like an especially difficult task, the Day Class is unaware of the truth behind the Night Class—their utterly gorgeous students are vampires. Ten years ago, Yuuki was saved from a vampire attack by Kaname Kuran, a Pureblood vampire. Now, Kaname is the leader of the Night Class, and Yuuki's disciplinary committee position allows her to see him again, making her feelings for him grow complicated. Meanwhile, Zero bears a white-hot hatred of all vampires and believes they can never live in harmony with humans. But a secret from Zero's past soon threatens the fragile peace of all at the academy, and things may never be the same again.

Takashi Katori is a big fan of online games, and so is his American friend Sarah. However, one of their RPGs goes too far, as their virtual world and the Lezarion robot that Takashi created for the game somehow mix with reality. Takashi is caught, but later the Earth Governement discovers that an evil scientist from the Moon (now a sort of abandoned colony with restricted access) is hacking into virtual worlds and security, so they force Takashi to pilot the Lezarion and, with Sarah's help, fight evil and protect the Earth.

In the original storyline as aired in Japan, Dairugger XV was simply an exploration robot, as well as an intended peace-keeping force. The Earth is in a time of prosperity. The president of the Terran League (the Galaxy Alliance in Voltron) launches a mission to explore beyond the galaxy. After commencing its mission of exploration, the starship Rugger-Guard is attacked by a ship of the Galbeston Empire. Dairugger, the super robot, is deployed in order to defend the Earth. It is somewhat by fate that they must help the people of Galbeston find a new planet before it explodes, and liberate it from its despotic Emperor. In the Japanese version, it does not have anything to do with King of the Beasts GoLion, as opposed to the U.S. version, Voltron: Defender of the Universe. There are three assault team units: Land, Air, and Sea. There are a total of 15 parts referred to as Rugger, which can combine together to form the super-robot Dairugger. The design of the 15 separate Rugger units came from the sport of rugby, since 15 players are required to form a rugby union. The U.S. version would rename the Galbeston Empire to Drule Empire, along with editing a fair amount of violence and sexual content to keep the show safe for general audience broadcast.

Hitomi Kanzaki is just an ordinary 15-year-old schoolgirl with an interest in tarot cards and fortune telling, but one night, a boy named Van Fanel suddenly appears from the sky along with a vicious dragon. Thanks to a premonition from Hitomi, Van successfully kills the dragon, but a pillar of light appears and envelopes them both. As a result, Hitomi finds herself transported to the world of Gaea, a mysterious land where the Earth hangs in the sky. In this new land, Hitomi soon discovers that Van is a prince of the Kingdom of Fanelia, which soon falls under attack by the evil empire of Zaibach. In an attempt to fight them off, Van boards his family's ancient guymelef Escaflowne—a mechanized battle suit—but fails to defeat them, and Fanelia ends up destroyed. Now on the run, Hitomi and Van encounter a handsome Asturian knight named Allen Schezar, whom Hitomi is shocked to find looks exactly like her crush from Earth. With some new allies on their side, Van and Hitomi fight back against the forces of Zaibach as the empire strives to revive an ancient power.
