To those who keep changing the character tags on this picture, the characters in the source image are tagged as Z1 Leberecht Maass レーベレヒト・マース（艦これ）and Atago 愛宕（艦これ）.

I know Atago and Bismarck kind-of look alike, but Bismarck is not tagged by the artist. Check the original tags if you don't believe me.

They don't speak German. That's Japanese
The translator choose to translate it to German

Wait, it was Atago?

Oops. Removing the German translations as it would be inappropriate.

I apologize for the confusion.
