That really bothers me that on page 12 she just goes "Hey guy from another world" and he doesn't even flinch... No one is suppose to know your a guy... Unless it's just a common phrase like "Hey guy over here".
I had a look at the raws. She calls him "hito 人" which is gender-neutral but more on the male side (like mankind). Other worlder probably would have been a better translation.
