Oshi no Ko

[Kraco]

So I assume the plot about the twins tricking her into thinking the gods sent them was just dropped.

Only a religious fanatic would bother to keep believing such a thing. It was a shock in the beginning, with really small kids speaking like that, but when years roll by without anything else happening, who would keep thinking about it? Especially after Ai was murdered shortly after. You might say that Miyako grew up as well and the advice she gave Ruby is actually something she follows herself.
