Coincidence
This is a Greek novel published in 1938 called...Eroica. Apart from the title, there is no other similarity to the manga; it's a dramatic novel about love and friendship, but still I thought it was a funny coincidence and I'd like to share it. The author's name is Kosmas Politis, he is considered an acclaimed 20th century novelist in Greek literature, although I doubt he has any fame outside of Greece. Here is a photo of the cover.
