The K-cell.

With the viscous attack of General Blan's army, and the death of the Pink Angel, Cynthia, still on their minds, the Green Tower goes on. However, when one of their androids, Android 1297, goes missing, every risk must be taken to ensure no further failures are made... To this end, a mission to save the future is made in the past. Megan, a girl just happy to be alive, and loved, loved by Master, must go back, back to a time before the bombs fell, before the virus struck, and complete the android's mission...not to mention rescue the android himself...if she can. If she succeeds...a gift like nothing else is hers to be had.
