After a disastrous attempt to infiltrate the world of pirates, Ron found himself instantly killed for violating the body of Im-sama. Yet, death was not the end. Reborn in Windmill Village, he awakened the ultimate power: the Pirate Overlord System. Its core ability, Heaven-Defying Plunder, was simple yet boundless: by binding a target to a specialized subsystem, any reward they earned would be returned to Ron tenfold. "Perfect," Ron grinned. "Now, it's time to turn this world upside down." He gifted Sabo the Ultimate Krypton Gold System and Ace the Daily Punch-In System. To Luffy, he bestowed the [God-Level Choice System]. Luffy: "So... if I punch that guy, I get meat? Shishishi!" Usopp (with the Strongest Pretending & Slapping System): "I command eight thousand elite divisions, with tens of thousands of followers across the East Blue!" Zoro (with the God-Level Sleeping System): "A fight? Let me take a quick nap. Witness the Three Thousand Dreaming Swords!" Sanji (with the God-Level Beating System): "You call that a kick? If we're true brothers, come at me and try to kill me!" Nami (with the Ultimate Treasure Hunting System) somehow unearthed the very treasures of the underworld with a single, casual shovel strike. One by one, Ron equipped the entire Straw Hat crew with their own reality-breaking systems, and in doing so, he reshaped the very fabric of the pirate world. .... Kaido: "The strongest creature? Pfah! Every single one of those Straw Hats is a monster!" Sengoku: "GARP! You call this a simple adventure? Your grandson is about to plunder the celestial gold itself!" Dracule Mihawk: "Roronoa Zoro... a prodigy? No. He masters my techniques in his sleep." The Five Elders: "Since when did the Straw Hat Pirates become the Ten Emperors?! And their true captain... Ron, the System Emperor?!" (This is a translated work ) Read more advanced chapters: patreon.com/J_Dragon

Kitazawa's grades at the Ninja Academy had always been mediocre. Uchiha Itachi graduated at seven; he barely scraped through at thirteen. Uzumaki Naruto became the savior of the ninja world at seventeen; at that same age, Kitazawa was still struggling to make Chunin. In this harsh world of shinobi, Kitazawa was what people called a fodder ninja: no talent, no bloodline, and no backing. To stay alive until the story's grand finale, he'd chosen the safest path-teaching at the Ninja Academy, a job he'd held for five years. "Another peaceful day in Konoha." Kitazawa rose from his seat and walked to the window. It was enrollment day again, and the training grounds were buzzing with life. He glanced down at the stack of new student files in his hands. Names leapt out at him, all too familiar: Uzumaki Naruto, Uchiha Sasuke, Hyuga Hinata, Ino Yamanaka, Sakura Haruno, Akimichi Choji, Nara Shikamaru, Inuzuka Kiba... and more. 'DING' 'Host has reached age six and successfully enrolled in the Ninja Academy.' 'Activating the Strongest Shinobi System.'
