The Mastermind Who Emerged from Garp's House

Kane transmigrates and becomes Garp's grandson, the big brother of King Luffy, and the bound host of a God-Tier Negative Emotions System. All he has to do is make people feel negative emotions to grow stronger! And so, the entire world of One Piece changes. Sengoku: “You bastard, Garp! Your grandson roasted my sheep!!” Akainu: “Kane, how dare you draw a red dog on my face?” Kizaru: “White Dragon Admiral, I'll fight you! I spent twenty years saving that retirement money, and you blew it all on a good time?” Imu: “Five Elders, issue a Buster Call! I want Kane wiped out. He drew a turtle on the outside of my cloak!” Luffy: “Big bro, you used my straw hat to dry salted fish?! I'm jumping in the river and drowning myself!” He gives the entire Marines a headache and is known as a menace! He makes pirates across the seas tremble in fear and is known as a demon! He keeps the Celestial Dragons from daring to leave Mary Geoise and is known as a scoundrel! Kane: “Call me the Emperor of Messing with People!”
