Dual is an
anime with
robotic wars and
parallel worlds(like
Lain).
Kazuki Yotsuga is the
main character and he is just an ordinary
high school boy. But there is one thing that separates him from his peers. He has
visions of a parallel world. Kazuki sees visions that other people can't. He sees robots fighting battles in front of him. But there is one that appears to the young boy often - a giant white robot that might actually be a
reflection of him.
But Kazuki is not all isolated from the
real world. He is still a
teenage boy, and is
fascinated by Mitsuki Sanada, the
most beautiful girl in school. When Mitsuki invites Kazuki to her home to be part of her
father's experiment, Kazuki gets
transported to another world...
The rest of the series deals with Kazuki trying to return to his original world.
