The Grand Line Starts with a Doran Sword

Diman obtained the League of Legends system and relied on equipment and skills to crush everything! "Are you the one with a bounty of 4.6111 Billion Bailey Kaido? Hey, have you heard of 'Yikku'?" "What? Bigmom stepped on Zeus and ran away? Don't be afraid, thank Jinx for the rocket!" "Tsk, what kind of demon-slaying order is this? Damn it! Look at my 'Cannon Screen' destroying everything directly." A man with a little girl, a bounty hunter who makes all pirates tremble in fear, a strong man that the navy covets, a pioneer that the revolutionary army worships, a devil that makes the Celestial Dragons tremble, me! It's a bounty hunter! Legendary Diman! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
