hmmm.. it seems like everyone is needing help finding their lost Mech Anime including me. I dont know if you would know the one I'm talking about.
The Anime is only 13 episodes long or 12 i cant totally remember, but the main character is this really shy kid who is put in the army, the mechs that they drive are manned by two people. His partner is brought in from another place and its a girl who they eventually getting together at the end of the anime. The last episode he takes her shopping and they go out for dinner and he pretty much screws everything up and then he chaces after her and gives her a christmas present. They both have dark hair, either dark dark grey or blue. but i cant seem to remember the name.
