That was quite an interesting series. I rather liked the jarring tonal shifts between cute slice of life and zombie horror. The series also did a pretty good job at not playing its hand too soon either. The first episode does a good job of just enough hinting that things aren't quite right, before the reveal at the end. To be honest I initially did think Megu was already dead because of how the rest of the group "ignored" her, but because some of the episodes flashed back to when she wasn't, I wasn't so sure, so the reveal was still pretty effective.

I really liked how the OP "decayed" more and more each episode - it made the cute J-poppy song more and more jarring to the tone of the series.

I wasn't too keen on the rather poor CG, but sadly this is pretty standard these days for most series without a budget. The series had some pretty effective horror moments but it didn't always hit the mark, and some episodes felt like they meandered around a bit.

Still, I definitely enjoyed it. A rather strange series where you're not really sure what to expect.
