#5 Sareee could be the NXT mystery woman
Sareee signed with WWE in February of 2020, but due to the COVID-19 pandemic and restrictions resulting from it, she hasn't traveled to the United States. She is still in Japan, where she has been waiting and working until it is safe to travel abroad. When she does make her way to the US, it will be as a member of NXT.
Xia Li and Boa are obviously both Chinese, while Sareee is Japanese. It still doesn't mean that WWE wouldn't use her in that capacity. It's also a way to get her into a storyline and accustomed to NXT.
If it is Sareee, it would at least allow her to film segments or have a stand-in until she is able to travel.
WWE has done a good job of making its stars from Japan seem like a big deal in NXT. On the main roster, it might be a different story. But the likes of Asuka, Shinsuke Nakamura, and Io Shirai have made huge impacts on the Black and Gold brand. Currently, Kushida is moving up the ranks at NXT.
While it is a long shot that the mystery woman could be Sareee, it is still a possibility. Fans never know what the Creative in WWE or NXT might be thinking, so it could be a surprise.
