No he's a boy...
Wrong Iori is a GIRL. I saw the raws, (spoiler) in chapter 9 the emperor who thought that Iori was a guy jumped Iori and touched Iori's crotch got surprised and opened the chest to find Iori's breast is restricted by bandage. From there it continues to chapter 10 the last chapter. Here's a URL to the website:
