I musts ax the manga pwns the anime by far! First of all the anime series has many characters that do not appear within the manga series. Additionally, the anime series, unlike the manga series, has not followed up with Part 2. As well as this, in the manga Reiji scores 31 on a test, whereas in the anime he only scores a mere 27 points. Also noteworthy, Reiji, have after acquiring Shinsaber, only uses the sword a few times in the manga. However, he uses it several times in the anime.
They Basically couldnt follow the original Manga because it was a monthly release while the anime was weekly so they came up with some filler moments and didnt animate the second part of the manga which is the best part of it.

However if you dont read Manga usually, this is a good watch. It indeed has some good fights and if you didnt read the manga then you wont be as disapointed as someone who actually read it.
The animation is very average and sometimes even worse
Overall the anime is not bad. (show less)
