That no translation page is actually just fanart of a japanese rap group "Hypnosis Mic"
crap forgot to mention, there actually has been doujinshi's of that group though, you can probs find loads around MyReadingManga
Nope, it's just fanart of Jyuto from Mad Trigger Crew. They have been releasing manga chapters for Hypnosis Mic to cover more of the story, but it's primarily focused around the music.
They have a yt channel where they release samples/full songs if you're ever interested: https://www.youtube.com/channel/UCLQwZQHMTRqeeUSzZt5ii6g/videos
