Yasuri's face fell for a moment because he didn't get to fight the dragon and the girl but he would get his chance later so that was alright. He turned to face the other boy who offered a supplumentary challenge. "Of course that would be fine, let combat begin." he said drawing himself into a stance that left his greatsword in a position to easily be swung to his defense from an assult from any angle. Yasuri carefully analyzed his opponent's weapons. They were light enough that his gravity control wouldn't make them unusable and given the arm blades his foe was most likely quick and agile. However the twin-blades also gave him the option of an X-Defense, nevertheless his greatsword should be able to smash through any defenses his enemy would put up. If the boy instead relied on dodging... it would be an interesting match.
