Prussia pic on the official site!
Edit: Translations for the blog are as follows, unless someone can correct it: (I'd appreciate it if you could.)
Volume 3 banquet hall(?)
(something like this... is the translation)
Rather, Prussia and someone's two-shot
Other character's two-shot was bothered by the position.
I take it to mean he was trying to do a two-shot with Prussia and another character but he was troubled by it and ended up with Prussia alone. Anyone with corrections can comment and I will change it. Thanks desearu!
