>  Yeah, since when in Aikatsu have idols changed types?

Well, if it happens as you imagine, the problem is more like why Koharu wasn't being a Cute type since the very first part? It would turn out as a contradiction.

It's not a pleasant fact, but S4 in season 2 also confirms to ignore the balance of type. Wouldn't be surprised to know that Venus Ark has no Cute idol.
