The year is 200X. Jin, Akira and Lena are three child hood friends who like mysterious things. One day in the library, along with the mysterious transfer student Ami, they find the "Akuma Compendium". They chanted an incantation in the book and, to their surprise, devils appeared. Ami then told Jin and Akira that they are the Devil Children that will decide the fate of the world. She hands them their Devil Risers. The group then pass through the "Door of Time" to the land of Valhalla where they fight an evil ruler known as Imperius who plans on conquering all of the world. The Nakama of Jin is Rand, a Sol Lion, and Akira's is Gale, a Hylon.

Due to family circumstances, Setsuna Kai is moving to a new city where he's supposed to live by himself in an apartment. As soon as Setsuna arrives, he witnesses a mysterious rain of rocks and barely escapes being crushed by an enormous boulder. Setsuna's new home wasn't as lucky, being completely destroyed by another giant boulder. Setsuna is distraught, not knowing what to do when he's approached by a scientist named Hiromi Kaname. Dr. Kaname's equipment apparently can tell that Setsuna is a "Devil Child", and so Dr. Kaname decides to take Setsuna to his laboratory.
