Twelve-year-old twins Ai and Yu Hayakawa take a mysterious subway to Wonderland to look for their missing scientist-parents. Wonderland is a hostile place, ruled by the petulant Earl Tyrant and his assorted hench-creatures. Ai and Yu are attacked by monsters and saved first by Lisa, a practitioner of the "Kigen Arts," then repeatedly by the taciturn, gun-totting Kaze. The first episodes are cluttered with characters who appear briefly then vanish. Although Ai, Yu, and Lisa do a lot of traveling, the series doesn't really go anywhere: the filmmakers seem more interested in showcasing the elaborate CG effects at their disposal than in coherent storytelling. The effects are very flashy, but they never meld satisfactorily with the drawn animation. Based on the popular videogame franchise, "Unlimited" borrows from Matsumoto's "Galaxy Express" and Miyazawa's "Galactic Railroad", but offers none of their mystery and magic.
