In due time, I suppose. But there's nothing really wrong with being seen as primarily a tag wrestler as opposed to a break out singles star, there can only be so many of those. And right now since they're trying to elevate as many people as they can with the smaller singles titles floating around I think the tag realm is the perfect place for Tomoka to get a chance to get "made".
Plus, she and Hiroyo together as a team are terrific; they'd probably get lost in the shuffle if they weren't a team. <3 JJ21, they had a BIG win in OZ.
