Arc System Works’ BlazBlue Cross Tag Battle‘s open beta has just recently ended, but it may seem like more unrevealed information has shown up from data mining the beta demo. Audio files such as the announcer’s voices signify that the following characters will round up the game’s full roster:

Izayoi
Nine the Phantom
Mai Natsume
Mitsuru Kirijo
Akihiko Sanada
Labrys
Merkava
Yuzuriha
Mika
Asuka
Yumi

The first nine characters are expectedly the remaining three characters that come from BlazBlue, Persona 4 Arena, and Under Night In-Birth respectively. But the unexpected ones are the latter two characters. When speaking about Asuka and Yumi, Marvelous’ Senran Kagura definitely comes to mind. Although it has not been officially confirmed yet, it wouldn’t be strange to see them appearing in 2D fighting games, especially considering that another Senran Kagura character Homura was added into the roster of Nitroplus Blasterz: Heroines’ Infinite Duel.
As a reminder, here is the list of 20 characters that will be available at launch.

From BlazBlue: Ragna the Bloodedge, Jin Kisaragi, Noel Vermillion, Rachel Alucard, Iron Tager, Nu -No.13-, Hazama, Makoto Nanaya, Azrael, Es
From Persona 4 Arena: Yu Narukami, Yosuke Hanamura, Chie Satonaka, Yukiko Amagi
From Under Night In-Birth: Hyde, Linne, Waldstein, Gordeau
From RWBY: Ruby Rose, Weiss Schnee

And here are the DLC characters that have been officially known as of the latest character ...
