Good episode. Some notes:
1. Dealing with the regional Meganees is a pain. Tohoku dialect is characterised mostly by more relaxed enunciation with some sounds being neutralised. Also some -be and -ppe suffixes~ppe~desu~nyoron.
2. Fukiko, Otomi and Kanade's names are all spelled with music-related kanji, which is hilarious.
3. [The identity of the idol Shion's chasing isn't much of a mystery if you're familiar with a certain other anime](http://i.imgur.com/s6SjwiK.png).
4. The following screenshot is a 100% legitimate translation of a line which is actually a reference to the last chapter of *Kodomo no Jikan*:
