From Takarazuka With Love

The Takarazuka Revue is an all-female musical theatre company. They have not, alas, performed a show based on Eroica (though they have done one based on Seven Seas, Seven Skies), but they did cosplay it for a magazine shoot once. Someone who speaks Japanese translated the text for me; I've misplaced the translation, but it says something boring like when the manga was first published and other stuff that we already know.

Here you can see a poster of the upcoming Seven Seas, Seven Skies Takarazuka performance.
