Yuuto was surprised, shocked and relieved all at the same time when he realized he recognized the sword style that had just saved him from his pursuers. The last time he had seen Zaikan was right before his exile and his subsequent spitting on the land of iron's policies, so to speak. He did not know what kind of reaction he would get from the man he once called friend. Would he be hostile? Would he try and chew him out over his abandonment of the land of iron? Would he insist on a duel right here and now, when they were in the middle of enemy territory? His friend was honourable, yes, but surely not to the point of putting it before reason. 

"...I'm surprised you would still call me friend." Yuuto said with a grim smile even as he continued running with Shira in his arms. "So, after a thirteen year old girl did the republic decide to send a samurai into Konoha too? Or is there another reason you're here in what must be the most impeccable timing ever for me?"
