You think so, Yoru and Yuki both have world ending abilities while Kenjaku is Kenjaku who was able to handle Tengen Choso and Yuki, while Yuki alone one shot a special grade curse like it was nothing.
star rage and construction are deadly,
realistically Kenjaku would’ve lost to Yuki if he didn’t have gravity to perfectly counter Yuki.
kenjaku doesnt really have any tech which can oneshot makora
we alrdy saw mahoraga adapt to yoruzo through her simple liquid attacks
same shit happens with yuki
these attacks are their trump card , they cant show it early
And till the time they show it , mahoraga alrdy adapted to them
and mahoraga also wont just stand there , this guy isnt just a tank
he is a crazy ass fighter
his portrayal / hax / feats are simply too good for ur avg special grade sorcerers
if magoraga was your average special grade like agito or rika, gojo would simply also tell him that he doesnt belong in the battle of the strongest like he told agito
the only guy who can actually keep up with the strongest
