Over the course of his journey, Guddo Rakku utilizes his swordsmanship to defeat those who dare abuse their power and bully the weak. He seeks out swordsmen to challenge them in a duel so he can become one step closer in becoming the strongest swordman in the world. Most of the time, he would use his sword to knock out his enemies and turn them in to the Marines but in rare cases, he would actually kill his enemies if they killed someone close to him and/or deems them to be too much of a threat towards the world.
