Awesome, now all of the wishes (from season 2 or 3, can't remember) have been fulfilled. This anime is amazing, but there is one thing that bugs me about it: they speak too fast there is no way I can follow it without the subs (at least for now).
They expected to work along with a normal coworker... but they were totally wrong. Marimo turning tsukkomi towards the ends reminded me of how wrong is having her as the stright man. It's just... not right.
