Only thing I can remember of 100% Hak is that he was the one who mostly beat the black beast.
And Black Beast is supposedly = Mu according to Hazama, so that don't bode well for Hak here.
I leaning Jack unless someone wants to correct me on any of this, do so.
The Black Beast is Ragna + Nu. Not Mu-12.
