There's this crystal, right, and it turns into a large shield. With guns. Or I think it was a crystal, as these mecha are blinged up with gold plating and ruby sapphire emeralds galore. And the giant golden blade that turns the school into a rainbow beam blasting flying ship? That can buy North America. All the bling is pretty much all the good in this. Relatively good, as that gun shield thing was pretty cool.
It's essentially crap, with kids manning four or so bots transforming multiple times, kicking gems that can end poverty, punching jewels, some sort of flying... stump thing in space. It's a trailer that doesn't get you pumped up for the series that comes after and since they couldn't even fit VOs in their budget, it's no surprise why it didn't get past this stage.
I don't know if there's a toy line, game series or any of that for this and considering that I most recently watched a quarter of School City Valanoir, I gave the animation a little something something.
