Can someone say me how much is different the manga from the anime? I saw very good reviews of the anime so I wanted to try seeing it, but I'm unsure if it's best to read first the manga or watch the anime.. If manga is different I would watch the anime first, because it is very short...
Well, personally I'd recommend Anime over Manga here.
Even though manga is longer plot-wise, somehow half of that plot seems more like "Everyone makes a pass on Aka"...(not that I wouldn't join them)
