theres a reason he was portrayed as the strongest of his era despite not having a domain
people do not get that its basically over for any sorcerer not named gojo/sukuna after this attack
he quite literally tears off the arm of his opponent ( which makes them unable to use a domain )
and kills them in cqc
this strategy is quite credible for sorcerers without a domain
even uraume does it
unfortunately tho their opponent is a healing maniac
and with the exception of gojo/sukuna and hakari there is no sorcerer who uses domain expansion in the starting of the fight , there is a reason its known as a trump card and only those guys can spam it
kashimo without his CT was portrayed on the level of modern era toptiers using hakari as an example
with his CT he is a whole different monster
if he can continuously blitz sukuna head-on
there is no modern sorcerer who survives his assault
