I saw an anime quite a long time ago and for the life of me I can't remember what the name of it is.
It's a magic/fighting/fantasy based anime and the main character is fighting, and then there is another entity that appears, he then gains this kind of ability, and gets given this kind of armour. Main character,
- Seen as a bit of a failure but has a very can-do attitude, and he always follows the rules -always carries a sword -there is a uniform that the characters in the team all wear, think there is black and green colours predominantly,
- Doesn't show much magical ability but doesn't really need it because he is really good with the sword
- His colleagues all have magical abilities, or powers etc…
- As he is fighting in one of the episodes he all of a sudden shows this hidden magical ability and gains a suit of armour
I know it doesn't seem like much, but those are the only things I can really remember about it.
