From ADV:
Woo Sang High is under attack! The entire student body is being terrorized by a duo of frightening bullies who have recently been released from a juvenile detention center. Guk Do and his muscle-headed sidekick, Chung Ki, are on a rampage and they have set their sights on Saang Tae, a brawny teenager with the courage of ten men. He alone will battle the fearsome duo, but there’s only room for a few at the top, and only one man can be The Boss.

The kingdom of Juushin is suffering at the hands of a cruel emperor. In order to stop his father's rule of tyranny, the crown prince will enlist the aid of a legendary assassin with reasons of her own for wanting the emperor dead.

One ruler, one schemer, and... one assassin.

After a decimating war against the androids they had built, humanity, though victorious, was forced to start living in shelters, isolated from the wastelands of the rest of the world, created by the damage the confrontation brought to the world.
Dr Gepetto, one of the brightest android creators of his time, died and left behind an inheritance of untold proportions, the only clue as to how to get it being a blue haired gynoid the old man had built and preserved for as long as possible even after his death.
The gynoid was reactivated, and she's attempting to escape the grasp of the new government.
And a hunt for the inheritance begins.
