Natori looked at Ryu. "Well next time face off against me. But I don't know if I'll be able to give as much of a challenge as Angelo." He lied. Even if Ryu had some very good offence, next to his defense it could simply come to a stand still. At least he'd back the older ninja into a corner. "Let's give it a try next time." He would listen for an answer, but he turned his attention away when their teacher spoke again. 

Natori didn't hesitate in stepping forward when Kombei-sensei requested that those who needed Ninjutsu training do so. "Ninjutsu is one of my primary fields. I believe I have a long way to go. I look forward learning from you Kombei-Sensei." He said calmly as he lowered his head respectfully. Once he looked back up he glanced at the others. He wanted to see who else shared one of his specialties. There was no doubt that he was ready for that. Better control over chakra, Easier usage and control of his abilities.
