This is the first volume of Zunguri Dango's BFW (Beast Fighter Wrestling) doujin series. For some godforsaken reason, someone thought it was a smart idea to upload the second volume first, and couldn't even been bothered to upload the fourth volume either. Doesn't help that all of Zunguri Dango's doujinshis are incredibly hard to find, and that most of their work cannot be purchased digitally, so I was even lucky to get this while I still could.
I have two more of the group's doujinshis available and I will upload them when I get the chance.
