How did you read it and thought it's another mugo, but not them all fused
Because that figure has been in other chapters away from the others?
He actually oversees the other three Mugos as in a repressed persona manner. Like he's someone with way to many personas in one body it's obvious the og one is the weakest yk. They literally merged due to a experiencing trauma again situation
Bcs thats not the first time he shows up????
Alright another mugo what now
