Hard to say
She's popular, but not extremely popular
She was in the most recent melty blood, but I don't think type moon is doing any other video game works that aren't remakes anytime soon
Maybe if there's a new extra/extella or something, but those games kinda sucked
The alternative really is another gacha, which I also have no interest in
It's too bad. There's quite a few characters I really enjoy who will likely never see outside of gacha like Lakshmibai, Achilles, Chiron, Voyager, Richard, and others
I was very surprised when Circe showed up to a new game
