What started out as a simple shortcut put Katsumi Liqeuer in the wrong place at the wrong time -- in the middle of a battle against mysterious monsters known as the Lucifer Hawk. Stranger yet is Katsumi's uncanny ability to wield powers that dispatch the enemy, powers that have the AMP -- the Attacked Mystification Police Department -- very interested. Now, with the additional pressure to join in the cause and the Lucifer Hawk out to kill her, Katsumi must decide to embrace or deny her fate!
In the early 21st century, certain people are exhibiting signs of B-cell growth, a condition that is incurable. Yuji is one of these, who chooses to become a "Sleeper" -- a person who is put into stasis until a cure can be found. The tranquillity of Yuji's sleep is interrupted 15 years in the future, in a very different world. Giant bugs known as Blue have invaded the Earth, eating its resources, and.. human beings. Now all Yuji can do is escape through the city with the ones who saved him from his inevitable death, towards Second Earth... mankind's new home in space.
