Oh man. Here’s the second volume to this story.
This doujinshi series just keeps on getting better.
You can see previews of the other two at the artist’s homepage
I’m really appreciate that alive decided to commission me to scan the second volume and he has arranged for me to scan the third volume too. Shame these might never get translated into English.
