This is one berserk Sakuya. No perfect and elegant maid here at all.

This is called "Meiling Manga" what'd you expect?

Well it's an indeterminate amount of time before the current canon, Sakuya obviously isn't a maid in the first place.

Mei-ling looks as if she knows perfectly well how to deal with this type of opponent.

@AfroThunda: Whence means "from where". So the addition of "from" is redundant.
