This seems to be quite an old anime. The main character is a teenager. There is this other world where the people there live in the knights and princess era, but with magic armor and stuff. Most of the story happens in earth I tink, or atleast the few episodes in front are. The main character can tansform onto a magic armor that is red and white in colour, mainly white and he might have a cape. He has a few companions, humanoid animals in the shape of a bird, a dog(?) and something else I think, in identical armor to the main charater and they help him out. Sorry guys i know this is rather vague but I got no pictures and thats all i can remember lol.
