I'm a fan of her design, but dear god are we getting a lot of fucking characters that are not DOA originals, and I think that's kind of the theme. Release a ton of girls and every four or five we will bring out one of the original DOA characters to boost interest and keep people hooked.
To be fair, someone on Discord theorized that we're going to be getting two tracks, with cut/mainline girls like Tina being on one track, and OG girls like Amy being on the other. I'm not sure whether to believe it or not, I didn't earlier, but after this, maybe there's some truth to it.
Either way, I suspect they're going to release Mila and Christie before the end of this year (since both girls' debut games have anniversaries this year). I suspect Mila's going to be STM, and Christie's obviously going to be POW. Lisa and Rachel will most likely be in 2023, since both Dead or Alive Xtreme Beach Volleyball and Ninja Gaiden have anniversaries that year. Lisa, per usual, will be TEC, while Rachel either is STM, or a STM OG girl comes in-between and Rachel ends up being POW (most likely the latter, since her home series was released on October). Regardless, NiCO will definitely be released in 2024 (DOA6 5th year anniversary, after all), and she's most likely going to be TEC as well.
