WARNING spoilers ( if you didn't read the manga) ( this comment is addressed to the author of the video) Sylpha actually knows about lloyd's power, she doesn't know completely everything, but still she knows that he is a lot stronger than her, so her reaction here is a bit unaccurate. she knew when she fought lloyd's clone controlled by grim that it was a clone, that's one of the things i'm talking about
I don't know if this story is true or not, but my friends said that originally Lloyd was meant to be a princess, but the editor said otherwise, so they changed it.
