True. I think Riku upgraded 00 Diver into 00 Diver Ace after only like five or six episodes. That's not even mentioning the upcoming the character in the RP - Sento Sakuraba - who despite not battling anymore has literally 100 custom gunpla builds in his personal collection. Plus another 100 straight assemblies kept on display in his store.

To clarify something, the Adam thing doesn't need to resolve immediately. In fact it makes more sense for it to be something that builds up over a bit of time, like building hype and publicity in a highly anticipated grudge match.
