Nightblade

Ryuu is a boy orphaned by violence at a young age. Taken in by a wandering warrior, he learns he may have more strength than he ever imagined possible. A quiet child, Moriko is forced into a monastic system she despises. Torn from her family and the forest she grew up in, she must fight to learn the skills she'll need to survive her tutelage under the realm's most dangerous assassin. Young, beautiful, and destitute, Takako is sold to pay for her father's debts. Thrust into a world she doesn't understand and battles she didn't ask for, she must decide where her loyalties lie. When their lives collide together in a Kingdom on the brink of war, their actions will determine the course of history. If they can stay alive.
