After reading up to 104 I can say with out a doubt that I want Yamada to beat the fuck out of that childhood friend loser boy, and he puts him in a proverbial goddamn body bag in 105.
I'm aware that this post is a year old, but in case anyone else comes along:
as far as I can tell, most other aggregator sites or hosts are uploading copies of the official English translation of this series. But Mangadex's rules expressly forbid the uploading of official English (or whatever other non-Japanese language) releases. So the only chance to see more chapters on here is to have a scanlator group do their own version and post it.
