"I..." Yuya's expression falls when he stares at Strange because no, he doesn't really have a way to calm her down. Gongenzaka called what was going on a poison, so he's not even sure she's in her right mind right now.

He turns back to Reira as she struggles harder in Yuzu's grip. He starts to shush her under his breath, reaching to wipe away any tears that fall as he gently strokes her hair.

"Reira, please, listen to me. Please, you trust me don't you? I said I'd keep you safe and I will. Whatever the Prince did, he can't hurt you anymore, so please listen to me!"

He's got nothing.
