I watched the subbed version, I don’t think it’s the same as the dub. But it’s very much a Pokémon/Digimon/Yugioh style mash-up. There’s a boy and girl who seem to be deeply in love,lol. And the girls father is a scientist looking for these relics in another world. So they visit the other world every episode to go searching for these relics, while also bumping into a Team Rocket group that also hunt the relics. The bad guys literally go blasting off in every episode, just like team rocket. It’s really cute kids show, but my goodness if you know anything about occult symbolism, demons,ancient gods. They’re everywhere, they’re used as monsters to fight, I don’t know if I ever learned the reason they even battle to be honest. Then the main plot has angels vs demons. I was really impressed by how good it was towards the last 15 episodes. The episodes building up to those were stills fun “adventure of the day” where they bump into giants, and monsters.

I you grew up watching Pokémon and digimon. It’s a fun show to watch.
