My point is Kairi deserved much better booking and casting than she was given. Even if she can't speak English, they could give her a manager, or, SUBTITLE THE PROMOS. Apparently, we have the technology to do that now.Yes and no.
Her wwe tenure was only 2,5 years long, and she won the may young classic, nxt womens title and womens tag titles.
She has no english skills, and she didn't have the same "it" factor as Asuka, so I think upper midcard with the occational main event was her ceiling anyways.
Maybe they should have used her for more big matches. But I'm pretty sure they were building her up. But once she let it be known that she wanted to go back to japan, any planned push was obviously put on hold.
