Pirates see him as a demon, while the Marines revere him as a god.
He draws his sword only to right wrongs.
In the name of demons and gods, he subdues the Supernovas, sweeps aside the Shichibukai, and brings the Four Emperors to heel! He personally brings the Great Pirate Era to an end and ushers in a new age.
"The devil judges the crimes of sinners. I only send them to hell."
P.S. Please overlook the somewhat cringey writing in the first twenty chapters. If you think the protagonist has it too rough, try reading further. Thanks.
