*looks him up directly on Wikimoon instead of just the Umino article*
Ah, he was the voice director for the first 65 episodes (which means DiC only, and dropping out during the Black Moon arc I guess), and also Rhett Butler/"Hercules" (Man, I would totally watch Rhett Butler: Journey No Densetsu if it existed (Because of Hercules: The Legendary Journeys, you see)). And a few other voices.
But still, he wrote a book about this? Or was it more of a general autobiography of his career that just happened to mention Sailor Moon? And he was still involved in the production I guess even when he stopped being the director, since he voiced some Metro Director rando in S and I think he was still Melvin? (What is the name of this book, and is it available to read online anywhere?)
Also, it's kinda awesome that the voice director himself played Umino. Now I'm picturing the DiC dub as Umino's names-changed-to-protect-the-innocent fanfiction about his own life. That's why only the parts about Naru/"Molly" are accurate. And the Shitennou's names are also changed to to protect the innocent which is why they're spelled/pronounced wrong and why there's "Malachite"! Only the famous superhero names and good old Queen Barrel are unchanged, because she's not exactly innocent. It all makes sense, I swear, no crackpot theories here.
