Yes, she is

"Yes" Mei nodded "I'm here to give the maze a try"

"Good" she smiled "Just in case, i'll remind you the rules"

Mei nodded again, and the **** promptly explained "Soon after you enter a guest will also be allowed inside, and as soon as he's there the hunt beings. You just need to keep him as far as possible, and if you are able to outrun him then a door will open and you'll be able to escape and get your prize. Should you lose, your hunter will be allowed to do as he pleases with you, and i obviously don't have to mention what will happens if you act too wildly, do i?" her tone was normal, but Mei could hear the grim hidden threat from her words and was quite sure she wouldn't be able to bear the consequence should she act out... well, at least not in her current state.

"Well, that's it. Go in and find an exit. If it's the right one you'll get a Sin Mark, otherwise it's your loss"

After a quick word of thanks toward the girl Mei entered through one of the gates, preparing herself for the trial ahead.
