Well, fan reaction to hosenfeffer has been lukewarm thus far. She’s a female character in a short skirt with stockings and “schoolgirl” shoes, so of course she’ll be popular (or at least not unwelcome).
Of course, she is affiliated with Capcom Fighting Jam(as many characters that we’ve already used before into one game to avoid having to do anything new), so some people won’t like her being in the comic (or PSP A3 for that matter).
I say, if you could find a way to put her in the book and make it work, then by all means. I think that the cast will be spending a lot of time on Bison, Akuma and Gill and won’t really care about an “Athena-like” schoolgirl character that harnesses the power of the sun through hair attachments.
She’d probably fit better in Darkstalkers or Rival Schools.
