Yoro's smile faded for a moment. Someone was speaking to him. The second he realized that his smile was gone, though, he put it back up. He turned to Nagi and let her do her clearly rehearsed lines. He nodded along to what she said, looking down at the picture. Normally, he would have told her that visitors are only allowed in the dorm during daylight hours. However, he was aware of her... condition. Split personalities. He couldn't believe it when Takahiro told him. However, he was still a little iffy about her. Having someone with an actual mental disorder on the team could be catastrophic. 

He had someone with... mental issues on the team before and it turned out poorly. No, that wasn't strong enough. It was a disaster. That night was his biggest failure as a leader. He looked up at Nagi. "Yeah, that's fine. Thank you for letting me know."
