Hi all,
I'm new here. I have been looking for an anime for years without any result. I watched a few episodes when I was a kid, and only remember some vague details. It began like this: there are two close friends (guys) who are some sort of martial art fighters, one is a bit more arrogant, the other one is mild-mannered. One day they seem to get sucked into a fantasy world where there are full of many other fighters. While getting there, the arrogant guy kind of loses his memory. The fighters in that fantasy world have the ability to transform into some animal armours when they need more strength, or something like that. The two friends also get that ability, one transforms into dragon armour, the other one transforms into tiger armour. I don't remember which one to which. Then they sort of go around, fight each other. And the mild-mannered guy tries to get his arrogant friend to regain his memory.

Okay...I hope this does not sound stupid but that is all left in my mind. Anyone know this anime please let me know. Thanks a ton
