I love Flandre's big, innocent eyes in this comic.

Let's see sakuya do THAT.

Since when can Meiling do that!?

Chinese kung-paw-fuuu is like force persuasion, just mention your name(effective if nobody gets your name right) in an unusual way at people and they fall asleep.

Well, Meiling can make rainbows, which is essentially light and water magic mixed together, so she might have manipulated the rainclouds to disperse.

...Or her power to manipulate chi, I'm just speculating here.

Blow away the cloud, put up a chi barrier or simply block the hearing of everyone is a few way she can do that with the power to control chi.
