Well I for one am not watching this for the "main characters" so to speak, depending on who you count as them but for Lehm and Valmet.
They are by the far my favorite chracters of the series altho I do also like Koko as well along with the others.
But it's the gruff old smoking geezer and knife wielding chick that make the series for me
Can't wait to see the mayhem unleashed!
