Today, Kei Katsuragi's only concern is the love of his life. It doesn't really matter to him that he has more than one love - after all, as a pilot for the Freedom Space Corps, he might be dead tomorrow! In the future, war has changed, and Kei is all too familiar with the horrors it can bring. Atomic, biological, and chemical weapons are all in use, but even worse than those are the dimensional weapons, ordnance capable of tearing apart even time and space! As it happens, his next mission involves one of these terrifying weapons, the latest risky gambit in the war over the space elevator on Earth. Fleeing from the warmth of his lover (and her father's gun) to the coldness of space, Kei fights to protect a team of engineers as they arm the dimensional weapon on-site. But when they get orders to pull out without detonating the bomb, Kei disobeys, unwilling to make the sacrifices of the day meaningless. His brash actions have dire consequences beyond just a big kaboom, as that explosion flings him into the future! There, Kei finds himself caught in an entirely different struggle between the militaristic Chiram and the mercantile Emaan - with himself as the prize! Will this womanizing hot shot pilot make it back to his own time, or is there something more to Kei being the "singularity"?
