Yumekui Merry begins with Yumeji Fujiwara, a seemingly average high school student. But ten years ago, Yumeji gained the ability to see the dream auras of other people around him. This ability allows Yumeji to predict what type of dreams people are likely to have next. The dreams of others may not be a mystery to Yumeji, but his own dreams have recently left him puzzled. In dream after dream, Yumeji has been pursued by an army of cats lead by John Doe, who claims he needs Yumeji's body to enter the real world. These strange occurrences get stranger when Yumeji meets Nightmare Merry, a dream demon seeking to return to her own world. Using his powers, Yumeji decides to assist Merry in getting back home. But Merry's very presence in the real world means that the barrier separating dreams and reality has been broken, and not all of the dream demons intend to come to Earth peacefully...

An unaired 26th episode that will be in the final DVD.

Twenty years prior to the story's beginning, an asteroid headed for Earth destroys Pluto. Due to Pluto's destruction, the asteroid, which is dubbed Thanatos, becomes temporarily stagnant. Now, in order to avoid Earth's impending destruction, the International Solarsystem Development Agency (ISDA) works on the "D-Project", and creates the "Dragonaut" after finding a dragon egg under the ocean. This weapon's primary purpose is to destroy the asteroid when the time comes. However, they soon find out that the asteroid is not their only threat, as powerful dragon-like creatures, which are bent on destruction, appear on Earth. After witnessing a murder by one of the creatures, Jin Kamishina, a lonely 18-year-old boy who lost his family in a shuttle accident two years ago, gets involved in the mysteries of the dragons and becomes the chosen pilot of the Dragonaut. Helping him on his journey is Toa, a mysterious girl who saves him from falling to his death after the creature attacks him. As they get deeper into the mysteries of the dragons, they encounter new friends and enemies, and also begin to develop a closer relationship. (Source: Wikipedia)

Dragon Quest is loosely based on Dragon Quest III. The names and some of the characters are familar, but the world map is smaller and a very different shape. The two main characters are Abel and Tialah. Tialah receives the legendary Red Stone from the Aliahan Village sage Master Yogi. Soon after, Tialah is kidnapped by the evil Baramos who wants to use the Red Stone to resurrect The Great Dragon and be granted eternal life. Abel swore to rescue Tialah and he is given the Blue Stone, which can only seal the Dragon once it has been released. (Source: AniDB)
