The world has been engulfed in a desperate, three-decade-long war against the BETA—an alien species that invaded the planet in 1973. Amid this chaos, a high school student named Takeru Shirogane suddenly wakes up from a terrifying nightmare where he sees mankind in utter defeat. Soon after, he realizes that his dream was nothing more than the recollections of his life in an alternative universe. In those memories, the Alternative V project is implemented, sending hundreds of thousands of people into space as a last resort to preserve humanity, while leaving the remaining billion on Earth to suffer a cruel fate. Yearning to change this grim future, Takeru joins a military base in Yokohama, which happens to be his former high school. There, he manages to convince the base's vice-commander and leader of the Alternative IV project, Professor Yuuko Kouzuki, to prevent Alternative V from happening. To ensure the success of Alternative IV, Takeru must pilot the gigantic humanoid machines Tactical Surface Fighters (TSF) alongside his fellow cadets. However, he has only two months to complete his training and exploit his partial knowledge of the future—lest the ensuing tragedy take place.

Even amid his personal turmoil, he is fortunate to find solace in the light of his father's love. But when the War of the Roses takes a turn for the bloodier, the fervent ambitions of Richard grow while his old loyalties splinter, threatening to taint his family's path to glory.

In a future-based disaster-ridden city with an enormous gap between the rich and the poor, it is hard to tell which humans are walking around with cybernetic body parts.

When a young girl with unbeliveable strength rescues him from a particularly dangerous criminal, Roy realizes that perhaps help can be found in the strangest of places. Joining together with a few others, they engage in a battle to find out the truth behind the giant conglomerates that are supposedly serving mankind and making life better. Solty, an android who has lost her memory, has escaped and is being hunted by the RUC Security Bureau. She encounters the bounty hunter Roy and he adopts her as his daughter after being hired as a bodygaurd for Miranda. (Source: ANN)

Dual and Dorothy, faithful computer antivirus programs, monitor and constantly scan for corruptions in the simulated worlds of the Box of Wisdom. Whenever a virus is detected, it—and in many cases the entire world as well—is forcibly purged. This routine occurs every day without change, until the deletion of a particularly large virus cluster reveals an unknown program—calling herself Remo—with no memory of her function. She offers a fresh perspective into the monotony of Dual and Dorothy's lives as her influence causes the two programs to realize that there is more to life than just their mission. No longer spending their time only watching over the worlds, the three girls start truly experiencing them. As they explore digitally recreated cities and landscapes, Dual and Dorothy develop a special appreciation for what they have, all while searching for clues regarding Remo's forgotten purpose.
