Moemura Glasses-Braid Iinchou is a mecha pilot, huh?
Edit: Yes, I gave him a 'London punk' accent (Cockney-ish, mostly) juuuust so I can fit in the word "best mate". Because "best bro"/"best bud"/"best pal"/"bro for life" doesn't quite have the same gravitas as ダチ.
He does have a rough, 'delinquent' style of speaking though. The usual convention is to translate that into, well, 'American punk' speech, which was what I originally planned to do, but then I got stumped on ダチ until I thought, "Hey, let's make him a British 'punk' instead!"
