It will happen eventually, but something tells me we won't see it after a few years and if this site is still up and running.
Now we have to analyze how the characters are doing at this point in the story. on the one hand if you decided to play the ian loser it is obvious that the fight against axel is lost and probably ian will be humiliated in public and then he will end up losing lena to axel, basically the wet dream of
mommysboiii.
Now if we talk about ian chad, then we can say that he and axel at the time of chapter 12 are equal in physical strength, if my memory serves me correctly axel has 8 points of strength and at the time of the tournament if you did everything right ian also has 8 points of physical strength that could increase to 9 or 10 depending on future decisions.
Now if we talk about fighting styles and experience, we can say that axel is a brawler, he lacks technical skills but he makes up for it with brute strength and he combat experience is based on fighting against other brawlers like him, which will leave him quite bulnerable when he faces someone who really has a fighting style.
Ian Chad on the other hand has an mma style combining jiujitsu and kickboxing respectively and by the end of his first rookie fight managed to take a win by submission or KO depending on whether he favors striking or the ground. In short ian chad has a better chance of winning against axel in a fight.
