this anime stood for a few years in my watchlist before i decided to give it a chance. don't be fooled by the lower graphics quality and seemingly mainstream storyline; this anime was a masterpiece. i enjoyed every minute of it, kept me engaged until the very end and it's full of emotion and inspiration. despite my feeling there are still some unanswered questions because i didn't read the manga, and it's a shame that the anime is already complete. but this one deserves a 5-star review.
