Re: Why is Asuka not challenging Becky?
In kayfabe, I don't know, she's focusing on her new life as a tag team wrestler.
Out of kayfabe, which is what matters here, they don't want Asuka in that spot. They never treated her like a true champion after her and Becky were done with each other, she faded away into irrelevance. She only ever beat Becky to put doubt in fans minds that she might not win the Rumble.
And now they've got Becky as their top woman. Charlotte's still in the mix. And they want to push Lacey. And with Asuka they're keeping her busy with Kairi to give her something to do.
No grand explanation but again, Asuka got her reign because Becky had to lose, she didn't do anything with it once Becky was out of the picture. And now that Becky has her belts, they've got Asuka down the card doing something else.
