Ryuutaro shrugged. Despite what he looked and acted like, he didn't mind to get himself dirty that much. As long as his face was fine, he was, too. You couldn't live as a traveling blader for too long without being a bit resistant to things like this.

"Well, then you should take your time to clean up", he smiled.
Actually he wanted those bruises to be taken care off as well, but he knew Hayato would just shrug it off... And even if Ryuutaro knew Hayato had so, so much worse, he still didn't like the thought of small wounds ending up ignored. They could sum up. He wouldn't like it.
But since saying it was no use now, he'd wait for a better moment to get that done.
