Everything on there is either being done by Viz, Media Do, or Medibang (The series’ with no credits) afaik. I believe both Media Do and Medibang are digital only companies. Apparently Media Do is known for doing a bad job of the Kodansha Mangabox stuff.
Yeah, this is a massive problem people are overlooking. Hinomaru isn’t barely even in acceptable English, with grammatical errors on almost every page. It’s also quite obvious the translator hasn’t read the series with some translation errors that just shouldn’t be possible otherwise. The Lettering looks like it was done by someone who just watched a Youtube tutorial on it yesterday too...
Haven’t looked into any of the other stuff yet, but if all Media Do’s stuff is like this, I’m not really sure how to feel. As great of an initiative this is, the official English releases should at least be in fluent English... And that’s without even bringing up translation issues. Like how does that even happen?
