In the distant future of 2999, humanity is divided into two warring factions, Terra and Ness, who battle it out with starships. Yamamoto Yohko, an arrogant teen pilot, is a renowned warrior in this ongoing conflict. However, during a mission, Yohko and her team become trapped in a peculiar temporal disturbance, reminiscent of the sci-fi hit franchise Star Trek, catapulting them back to the present day. With no memories of their past, they assume the roles of average high school students. But when unforeseen circumstances bring them back to their ship, the TA-29, Yohko and her newfound comrades join forces to fight in a war that looks strikingly similar to a classic arcade game, complete with 100 yen ignition costs!
