It has already been established that there are characters who are stronger than Ran. Makoto definitely is and Akai is strongly implied to be as well. She was more or less evenly matched with Irish.
I can see her fighting it out with Chianti, Korn, maybe even Belmot, but Gin is what amounts to the main Antagonist and what's more Akai's sworn enemy, so if Conan doesn't get to take him down personally, Akai will.
