Here's a series I picked up late into the season, hence it's omission from the Midseason review. I watched the first episode out of interest but it didn't stick. Little would I know that it'd be very similar to the situation I had with Sakamoto – the first episode doesn't really do the series justice. It's kind of fitting, really, as the series has a recurring “don't judge a book by it's cover” theme. Keep up with it, and it's a fun series with a very happy and pleasant tone.
Just fyi, I'll refer to this series exclusively as "Tanaka-kun". It's full title is a bit of a pain to type out multiple times.
