Yuuto could not help but give a sad sigh at the mention of the land of iron being a part of the shinobi republic. "It is as you have said," he said, "I am a sightseeing samurai, and I did indeed just happen to stumble upon the Hokage sparring. And, regrettably, the land of iron is still part of the shinobi republic." he said without any trace of lying - it was technically all true. 

"However, if you're suspecting that I'm here to spy on the hokage or to gain any information that might harm konoha for the republic, don't worry." he said, raising his hands in a gesture of innocence. "I'm no longer affiliated with the land of iron."
