Yuya looks surprised to hear about the ward, but it's definitely a good surprise. He glances around their large group again before pointing to himself.

"I have a shield and the warding spell. They won't work if I'm moving, but if we get stuck then I can protect people. If we can avoid splitting up..."

Well, that would be ideal. He's not sure if splitting up is a good idea, but if they do ge should probably go with the group he can protect best.
