The only characters that I'm missing are the buriki one ones (xD) I saw in that roster a lot of potentials characters, like kim student, the boxer etc.
Savage reign don't fit that well in the game though, and the garou ones, I don't know, it seems stupid to reboot the series and forget all the advances with the lonely wolf version that appeared on XI, but I want to see other characters, for example, they could introduce Marco, both Kims, and hopefully Hotaru
