Did Machiko Soga do a voice in this one? If it's the series I'm thinking of, I think I read somewhere that she was part of the cast list.

Yep and yep. Says that she appeared in episode 36.

The 7th episode of Ultraman R/B was really good, probably the best one so far. I like that it built off the previous episode. Isami was very relatable in his fear of hurting others and having to work on his own.

Relatability is definitely R/B's strong suit. The characterization in that show is down-to-earth in a way I don't think I've seen in many other toku shows. It's essentially an Ultraman show about people who don't care that much about Ultraman, and I still think there's something kind of magical in that. Hope you enjoy the rest of it too!

I mean, there's certainly one man in it who cares way, way too much about Ultraman! :p

Exactly! An overly obsessed Ultraman fanboy is one of R/B's biggest villains! If that isn't a statement on where its priorities as a series lie, I don't know what is.

R/B: Has a main villain, one of whom's flaws is obsessing over past Ultras to the point where he hates the main duo.
Me: Finally, a show for me!

(I promise I'm still watching Z, more hot takes on that maybe coming soon!)

Hey so what's the deal with Noa, Nexus, and The Next? They're like the same power source but different people right?

From what I understand it's basically a backwards Pokémon evolution - Noa is the original and the strongest, The Next is a devolved version of Noa and Nexus is the most basic, weakest version of Noa.

I haven’t seen a single episode of the shows where those characters appear in though. Except the Nexus guest-appearance in Ultraman X I guess.

Spoilers for the Nexus series ahead:
So Noa is the original and most powerful guy, except he got kneecapped in the distant past and lost a lot of his strength. He bonds to a human in Ultraman: The Next movie, and thus becomes Ultraman The Next. He levels up a little in power to become Nexus, and as the series increases he both switches around hosts and gains power until he's able to regain all his power in the final episode and become Noa again.
