There is a strong likelihood that Inoue will stay in the division for a while if he becomes a champion. As long as Casimero remains the top contender, there is a good chance that the fight between them could materialize. The key factors that may come into play are the negotiation process and Inoue's genuine willingness to face Casimero. A potential matchup between them would finally put an end to the speculations surrounding Casimero and Inoue. I am eagerly anticipating the Fulton vs Inoue fight, as its outcome, hopefully favoring Inoue, could potentially pave the way for Casimero to challenge him.
That's a high possibility that Inoue would stay in this weight category as he has yet to prove that he can bring his power to a higher division. If he wins (Inoue) then a unification fight with Tapales is the biggest for this division to happen thus far and a fight with Casimero will only materialize if the latter will keep on winning and become a mandatory challenger as calling out Inoue without a belt or something might not interest the Japanese Monster to fight him as he has nothing to gain in fighting Quadro Alas.
Yes, and it will be far the quickest road to unify all the 4 belts in the modern era and he could make another history. This is just his first fight at super bantamweight and if ever he wins he will go for the unification with Tapales at second fight.
Then it's going to be difficult to retain all the belts, because each body will have it's mandatory fight so going to be hard which one is he going to chose and which belt he will vacant so that other fighters like Casimero can fight over it.
If Inoue is successful in pursuing a unification fight and becoming the undisputed champion in this division, then Casimero would have no chance of fighting him anymore. Similar to what happened in the Bantamweight division, after becoming an undisputed champion, Inoue decided to move up and vacate all the belts. Casimero might become a champion, but only after Inoue vacates the title, which would leave him still chasing Inoue as he would not get an opportunity if Inoue decides to move up once again.
That's something that will avoid Casimero to have that chance again, as Inoue might try to climb up again after
winning or after unifying all the belts.
Unless Casimero will have that chance fighting Tapales and snatch the belt, that might be his chance if Inoue will push and try to
unify all the belts in 122lbs the same way he did from his previous division.
All will be on Inoue's decision making and not to forget depends also on what will be the outcome of this fight.
