This is a long time coming. We didn't even know the omake existed for a while after the volume came out, then it was a rollercoaster trying to obtain HQ scans for said omake. The second volume has another omake as well, and a short one-shot by Endou Tatsuya, which we have HQ scans for now. Though I don't know when those will get released yet.
Enjoy the release!
