He liked it enough to whitewash:

I'm happy that the show did not attempt to explain the situation with Muryou. Some things are fine to remain mysterious because they ultimately don't matter to what the show is about.

Oh, brother. I am pretty sure this was unintentional, based on the small exposition fragment in the end (with chibi Muryo in a Roman toga). It may be that it came out better that way, but it would be even better if the little segment was missing entirely. But what does it matter now, it is what it is, and it is a great show. I did not see a direction this strong until Oh Edo Rocket came about.
