Right, so what Rob said. It's just that the I feel like the reasons for the first season villains being in Tokyo were the weakest. There are two reasons that are side objectives: The first is Beryl's crush on Endymion, and love/lust is as good a reason as any to make that mistake. The other is finding the seven great youma/rainbow crystals, which are anime-only. But if the goal is obtaining the Ginzuishou, then it's a necessary step.
It's just a strategic error. If you need more life energy (whatever that is) to feed your Metaria and field your forces, you might want a stronger force before you start facing foes. If you face your enemies and keep losing or only partially achieving the objective, you are doing it wrong. All while choosing the ops and thus choosing your own battlefields. And these are the same people who took out the Moon Kingdom, so they should be able to plan. On the other hand, they've been trapped for N-thousand years with a pet Elder God so they may not quite have the mental capacity they used to.
