In the past, Haruka's hometown was destroyed, and her parents were killed there.
Behind all this was the military conglomerate Yakou. That day she decided,
that when he grows up he will avenge all that he has done. Now she is an LFO pilot in the Civil Justice League (CJLeague).
Since Haruka works in a private company, she sometimes takes part in PR activities,
which sometimes includes various erotic acts, of course, at Haruka's will.
