I finally watched it and it's not so bloody, as much as a match where you fear for the participants getting CTE from the headbutts and chair shots. I don't think I've seen something that traumatic looking since that Fu-Ten tag match with Ikeda, Oba, the dude from NOAH I can't remember... anyway, that one had a LOT of headbutts. This was worse than that, and it's hard to say that about anything BattlARTS related. It definitely wasn't as good as the DEAN chain match but still shocking in its way.
EDIT: The NOAH guy was Makoto Hashi! He had a headbutt-based offense, which was perfect for that match. I cannot recall who the fourth participant was.
EDIT II: God, 2010 feels like a long time ago -- and for me personally, in terms of life, it definitely was. https://www.youtube.com/watch?v=C43lKfKR6E8&ab_channel=SegundaCaidaPhil
EDIT III: (Wow, I haven't had this many edits in forever) I watched the entire 30 minutes of that match and it's like watching Street Trash or a Frank Henenlotter film, or combining peanut butter and an apple. It's two things that absolutely aren't supposed to go together, in theory, but they work perfectly. Comedy wrestling and the most harrowing of shootstyle should not work. At all. But this makes it work. I don't know how else to describe it; Phil already did a review (which I need to read after writing this), but it's something I think needs to be watched to understand. And yes, there is blood. More welts than blood though...
