Attack on Titan "Visitors suddenly"

It is the appendix DVD of "Attack on Titan" Volume 13.
My friend said that DVD was very funny and she lent me it.


　　　　　　　　　　　　　　

The title "visitors suddenly"

Is Jean the leading role? 

I seem to have nothing to do with the main story.
Comedy DVD? ? ? 

Let's watch DVD on this weekend.

By the way, Volume 13 It was very interesting！
