A release of Puella Magi Oriko Magica Chapter 2 by Anon Scans has been seen over at the net, being the first ones to release ahead of Yurikai. We don’t know what’s taking too long for Yurikai to make a release, probably they’re polishing the chapters before release. We’ll add their links here once they’ve updated their site.
Anyway, here are the download links (via /a/ scans).
