Ryuutaro looked at his clothes. Yes, he was clearly looking messy again. But he figured that he'd still feel more comfortable wearing his own things, however bloody they were.
He even felt unsure wearing other clothes around Hayato, so he could live without having that feeling around a bunch of confusing strangers. And he didn't want to leave Hayato's side for a moment either.

"I'm fine like this, thank you", Ryuutaro answered putting on a fake smile, "And some more information would be helpful... Unfortunately I don't know too much about any of this."
