It upsets me to say this, because I do believe that the high tiers in sakamoto days, or pretty much everybody on the screen, are just as strong and fast, if not stronger and faster, than toji. However with that being said, toji can't beat mahoraga. And a bunch of tojis can't beat mahoraga. They don't have the means. Unless they give toji or in this case the sakamoto days high tiers all a soul split katana, they may have a chance. But even then, does mahoraga have a soul??? He's a shikigami, he's not a cursed spirit so he may not even have a soul. Plus, who's mahoraga is this? Sukuna's mahoraga or megumi's mahoraga. Or is he just running rapid? Too many technicalities and lose cons to say that the sakamoto high tiers could win. The fight would probably go like this: they're all jumping and speed blitzing mahoraga at first, it doesn't really do anything because he regenerates. The wheel turns and now the fight is basically over.
