Got linked this in a discussion group on Discord.

Apparently it's one of Beaver's works - the guy who did Angel Corps.

Anyone have any more of this, including the obvious escalation?

Please note that I don't have a pixiv account, and have more than enough online accounts already so I don't need any more - if you can post it here, or point me to a site that doesn't need a sign-in, that would be great. :D
