Yuuto was honestly a bit surprised when he was asked if he was going to serve Konoha. While it was true he held no more allegiance to the land of Iron, he still held proud feelings for it - he could not allow himself to be dragged in an unjust war against it. Even less so for monetary reasons. 

"Joining Konoha? I will be honest, I have not considered it." he admitted. "It will be hard for me to take arms against the land of iron, but I will fight for whichever side is just - and so far, all I can see are the Republic as the aggressors. But I highly doubt Konoha will allow a man from the land of iron to join them, no matter what his current relation to that nation is." he pointed out with a grim smile.
