Fuji is not weakest.
He's a swordsman means that he'll be Zoro's opponent which means that he should be second strongest and should be next to Akainu who's going to be Luffy's opponent. It can be implied that he's the strongest of current 3 admirals.
Holy shit, the bullshit is strong in this one.
Just because he has a sword he is second strongest because Zoro is too ? Lol the arrogance.
Why says that Fuji will ever fight the SH's, he seems to be one of the 'new' marines who doesn't follow the absolute justice ideology of Akainu just like Smoker, Coby and Garp etc.
Besides, that fighting the second strongest thing hasn't happened for a while now. With Fujitora, Doflamingo and diamante running around. Are you sure Pica is the second strongest on Dressrosa ?
Was Monet the second strongest in Punk Hazard ? Was Hyouzou the second strongest in Fishman Island, or would he get steamrolled under Wadatsumi ?
He hasn't fought the second strongest since timeskip. The second strongest is now reserved for outside characters to show-off their growth, like Jinbei, Law, Sabo (and possibly Kyros).
To call Issho second strongest just because he has a sword with Kizaru still running around and Green bull who is unknown is just silly.
Also Akainu isn't an admiral anymore, so also for that reason he should be taken out of the equation.
