Mark my words, Asuka will not appear in main story at all just because she was shutted in private school by Lili (which explains her outfit).

But seriously, after King appearance in story cutscene her absence along with Jun (as a living person) is really weird at this point.

xорни гриб 🔞 Either Asuka and living Jun are being saved for the Launch Trailer (as in the week of release), or their parts are, shocker, being saved for the story mode to have SOME surprises.
