Hail pole cat

literally Misogi Kumagawa having the most overpowered ability in existence

light can literally one hit u. you die in a matter of seconds

Think again

Thanos logic. Go for the head

he can bring himself back to life

but he's dead, the brain cannot make any more moves.

"The brain can not make any more moves"
It simply means he can't pull off the move, because he has already severed connections to his body from his brain
I am well aware of this, but if he cant even think then he cant even use the move!

he doesnt need his brain cuh
its automatic that his own ability does it itself

when a person dies blood stops flowing to their brain so itll die too
it doesnt matter how he dies he will come back

It's not really stated, and you could have said that from the very beginning

i read the manga cuh

Light Iamgay?
