I believe you're already aware of this, but Gensoukyou is protected by two barriers.

Your barrier, and the Great Hakurei Barrier...

Indeed. I, being a youkai, will be fine, but...

Or rather, I should say my barrier will be fine exactly because I'm a youkai.

However, she's different.

Please, do not make me say everything out loud.

I won't ask you to give your consent.

However, I will ask that you keep quiet for a while.
