Busty cadet Misaki and the other abnormally large-chested women of the Allied Forces Military Academy are subject to rigorous training. Misaki begins to have some doubts -- OK, a lot of doubts.

Picking up where its predecessor, Divergence Eve left off, Misaki Chronicles opens with busty police cadet Misaki returning to Earth after successfully fending off the space-station attacks of an alien race of robots known as the Ghouls. But the inept Misaki has inadvertently triggered a time warp that allows the Ghouls to alter human history, prompting her scantily clad police-cadet cohorts to jump into action to combat the alien menace.
