The male mc has no magic but he goes into an “understanding” mode where is eyes get all cloudy. He has to get translation magic from the church but it makes him ill or something.
He might be a demon lord because he knows Japanese and helps translate a forbidden book.
At least 2 of the world’s heroes are his companions. Both are female one is a beastman.

I can't remember the cloudy eyes part, but the translation magic that makes him ill must be this one
