Pirate's Demon Rubbing

Rhodes, who traveled to the world of pirates, became Luffy's biological brother and Ace and Sabo's favorite brother. He has a lot of friendship with the red-haired Shanks. To be honest, Shanks is half of his teacher. After all, Rhodes learned swordsmanship, Haki of sight and color, and Haki of weaponry from Shanks. After joining the Navy, Rhodes' system successfully unlocked the demon rubbing. Ps: Devil's rubbings: Various rubbings with devil fruit abilities have two advantages when compared with devil fruits. 1. Possessing a Devil's Mark does not mean taking a Devil Fruit, so possessing it does not require you to bear the side effects of the Devil Fruit, that is, you will not be afraid of sea water and seastones. 2. The host can equip and use multiple demon rubbings at the same time.
