Code Geass

[Li Xingke, part of the Chinese Federation diplomatic party to Area 11, is accosted by two Britannian security guards]

Britannian security guard #1:
May we have what you're carrying, sir?

Britannian security guard #2:
Our security is perfect. You don't need to carry that antique weapon here.

[Xingke unsheathes his sword, slashes at the two guards, and sheathes back his sword in one stroke; the guards are unharmed, but their severed belts then drop to the ground]

Gao Hai:
Xingke! That was rude of you!

Li Xingke:
Please forgive me. But I hoped it would offer you and the other Britannians a better understanding of the Chinese Federation.
