dude I think he can do that at any point when there are no 6 eyes around, we really do not know how the bloody hell a 6 eyes user showed up when kenny killed the 6 eyes baby prior.
Then the gojo clan wouldn't know anything about the past then, neither would it be one of the three big clans dude. What I mean by that is that, Kenjaku would have certainly tried this, because Six eyes is tied to the gojo clan bloodline to begin with. It wouldn't exist even if the fate of the six eyes is tied to Tengen. Because how else could you have a gojo clan member if there isn't a gojo clan bloodline?
Clearly they weren't just a bunch of fodders, with or without the six eyes users.
So my point still stands that Mahoraga is a exceptionally great tool to kill the six eyes users with limitless ct already. given the fact that untamed Maho killed that person.
are you certain about that? I am more than sure a good chunk of the 6 eyes users could end maho.
How many has limitless ct and six eyes at the same time? very few. It's also why HP is so rarely known to few people. And we know a untamed mahoraga murked a six eyes limitless user.
And yeah, I'm pretty sure the Zenin clan and Gojo clan being enemies with each other over conflicts like this event from 400 years ago, is quite telling that none of the six eyes user were opponents for Maho whatsoever. Heck, nobody in Zenin could ever tame Mahoraga whatsoever to begin with, in history.
You can also try to team up and exorcise it, but it's still said that nobody has ever succeeded whatsoever. Considering the enmity between zenin clan and gojo clan, there are bound to be sparks between six eyes users that are non limitless users, so there's that. But ignoring that, a head of gojo clan, specifically one with six eyes and limitless ct, lost. Gojo himself thinks that is noteworthy, so it most likely isn't some newbie scrub limitless user but one with blue, red and purple. As Megumi says they died to untamed Maho.
That being said, this still doesn't address the fact that, upon obtaining a shikigami successfully, you can further strengthen it. Mahoraga, who's base stats are 3F level, would be further strengthened if controlled. Meaning: A almost guaranteed way to kill any six eyes users no problem. And even to completely destroy the gojo clan. Kenjaku can also camp and wait for the current six eyes users to get old before striking as well, and eliminate the clan in one fell swoop.
