Episode 1: "Life Sympathy"
While working on a new city hall, a young construction worker unearths a strange artifact. Annoyed at the
prospect of archeologist hordes nosing around, the foreman orders him to ditch it. At that moment, time splits
into two threads, one in which the worker tosses the artifact, and one in which he pockets it. Two decades later,
in one of those universes...
Kazuki Yotsuga is known for being something of an odd duck - he zones out in class, envisioning
titanic robots battling along the skyline, which he writes about on his webpage.
He's amazed when school beauty Mitsuki Sanada confesses to being his biggest fan, and takes him back to her
palatial home to talk more about his visions. However, once there, Mitsuki's mad scientist father, Ken Sanada,
pounces upon the hapless boy, convinced that Kazuki represents the best hope for his theory of parallel universes.
Maniacally, he straps the lad into his experimental Super Ultra Deluxe Parallel World Transporter, intending to
send him into the next world.
Kazuki awakens in the ruined Tokyo of his visions, where killer mecha battle it out for real.
Episode 2: "My Home"
Alone in this parallel world, unrecognized by his family and friends, Kazuki, who has an uncanny ability to
pilot Hartzenen (mecha), gets a lot of attention from Earth Defense Commander Ken Sanada, the parallel incarnation
of the very man who sent him to this alternate reality in the first place. Alas, this Dr. Sanada has been too
busy fighting a world war to build a machine like his mad scientist counterpart, so there's no sending the boy
back-at least not until they win the war.
Still reeling, Kazuki encounters the Mitsuki from his own world, who has already been there a month.
Meanwhile, the enemy issues a challenge, and Dr. Sanada feels as if he's got an ace in the hole...a boy named Kazuki.
Episode 3: "Illegal Guy"
Despite pleas by Mitsuki and U.N. liaison Akane Yamano, Kazuki isn't ready to leap into Hartzenen as a pilot
in a war in which two superpowers resolve territorial disputes by wrestling giant mecha at each other, but the
crafty Sanada coaxes him into the cockpit of his beloved Hartzenen.
While in the hangar he meets another pilot named D, an odd synthetic girl whose "soul" was rescued from the
alien artifact, from the first episode, and placed in a bioroid body. He enters battle the next day, however he
only leaps into to save the day when he perceives Mitsuki threatened. However, in the post morten, Kazuki learns
that these combats are seldom deadly-were she truly in trouble, Mitsuki would have surrendered.
Episode 4: "No Disguise"
Dr. Sanada has come up with a way to prevent Rara from discovering their new pilot is a male - a flight suit for
poor Kazuki designed to give him a girl's face and figure. Assured by Dr. Sanada that no one will know who he is,
he introduces himself to the support crew as a girl, and then is mortified as they burst out laughing-stung by a
remark Dr. Sanada said the day before, Mitsuki has told them his secret.
He runs away, eventually arriving in the hangar where he meets Yayoi Schwael, the woman pilot he rescues in
episode 1 - her ability to pilot Hartzenen was burned out of her in her last battle. It seems Yayoi is a little
sweet on Kazuki, something a spying Mitsuki picks up on immediately. As Kazuki heads into battle, Dr. Sanada
promises he'll have a proper male's suit made for him next time. And is that a note of jealousy in Mitsuki's voice?
