He doesn't bother with the illusion, as sick as it might make him. He keeps cutting through things to protect the group. If he were in his armor he could do more, but he's not sure where Yurine is. He knows his soul is safe though, and that's what matters.

He ignores any injuries he's getting from things hitting him, dodging out of the way the best he can. He doesn't care i he's bloodied or bruised, what matters is keeping other people safe. If he can't attack, at least he'll defend.

Otoha hears Mami's offer but ignores it for now. He's fine. Everything's fine.
