There's a pause, and then Yuya nods with just as much firmness. Rita's right, and if she's this certain then he'll believe it, too. Isn't it what he's been trying to get Ignatuis, a second chance?

"Then I'll believe in it, too." He turns to Igantius his expression less uncertain and starting to confirm to him--and then there's an awful sound and a blade through him.

"No!" Yuya lunges forward with sudden force, arms outstretched as he tries to grab hold on light Ignatuis' arm, tight as he can to try and get him to halt. "Stop! That's still part of your soul!"

He's completely focused on trying to interfere with the bloodshed, he misses anything else happening around them.
