Episode 6
Edit: I just decided to check out the english dub of the first episode. Holy fuck. I'm not one of those "super nippon seiyuu glorious" types. If a dub is good, it's good. But this isn't good. This is god awful. It sounds like amateur hour or something.
It gets waaaaay better. I can't say exactly where the English VA cast finds their groove, but they do find it.
