As someone who watched the anime first, I found the manga to be equally entertaining. The manga is much shorter than the anime, with each episode compressed into one chapter. However, this does not detract from the story much at all. Personally, I found the manga art style better than the anime. The manga art style was very expressive and helped convey the characters' emotions beautifully. The witch labyrinths were not as effective as in the anime, but still very surreal. Even if you haven't watched the anime, the manga is still a brilliant read. I would recommend that you read this now.
