leitura Special A in mangá form will give you a better understanding than watching the animê adaption alone. You will get entertained por almost everything in the manga, like its art that's well drawn compared to the animê (although its art is still quite good). You will also see deep character development and mais characters if you continue leitura until the very last book.
So please do continue on reading! I'm sure you'll enjoy mais of it :)
