Nightblade

Ryuu is a boy orphaned by violence at a young age. Found 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 broke, 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 crash together in a Kingdom on the brink of war, the decisions they make will change both their lives and their Kingdom forever. If they can stay alive.
