King-Ohger is set on Chikyu with its own 2000+ year history. It's a breath of fresh air when literally all tokus (at least PR, Sentai, and Rider), take place entirely or mostly on Earth, with a few exceptions. Even when they have lots of lore involving aliens and other planets, like Abaranger. If King-Ohger ends up incorporating Earth into its story, then I wouldn't want to see it until episode 40 or later (the final arc). I'd rather it doesn't take up much if any screen time.
It will be interesting to see how King-Ohger vs Donbrothers handles this, it would be cool to see the casts travel to Chikyu, or even back and forth. But that feels like some serious wishful thinking, that kind of thing is out the ordinary in the toku genre.
