Austria - Yenra Picture Wiki
Austria from Hetalia
Austria is an elegant-looking young man who has interest in the arts, specifically in the piano.
He is mostly known for taking control of Italy after the Italian Wars (present in the Chibitalia parts of the manga/anime) and having Italy as his servant.
Austria's relationship with Germany is seen as love–hate since they merged and became allies during World War I, but Austria's presence annoyed Germany greatly.
