So the main character is heading to some place where the elite warriors are trained. He has a unique fighting style that uses a short sword in one hand and something like a dagger in the other. The dagger thing is longer then a normal dagger and has something at the bottom of the blade that he uses to trap his opponents swords when he blocks with it. The main thing he does is block the swords like that and onces he traps the opponents blade he uses his sword to brake the trapped blade. So the first part of the story is him travelling to the place but along the way pirates attack the ship and he joins the pirates and claims two girls (who one or both might be related to him in someway don't remember) to protect them. He eventually leaves the pirates and goes to the place to train where you find out more avout his unique fighting style. I don't remember much past when he arrives there. Not sure if I finished the story or not. I hope someone can help me find what I am looking for.
