The main character of Shirobako is the production desk Aoi Miyamori, charged with ensuring timely delivery of episodes, and she’s very good at it.
That makes this more than a little ironic (not to mention frustrating):
Perhaps Mr Mizushima needs to find himself a real life Aoi to work some miracles…
Oh well, in the meantime have the charming, and quite cleverly animated, second ending song for Shirobako sung by the five lead voice actresses under the name Donut Quintet. 🙂
And, yes, there’s five versions of the ending animation, one for each of the lead characters. Finding those is left as an exercise for the student.
UPDATE 21/03/2015: The episode is now available on http://www.crunchyroll.com/shirobako but I’m not saying anything about it for at least 24 hours. This is not an episode that anyone should spoil.
