I Am a Navy Instructor, Fighting at Marineford to Enforce Justice

Rod transmigrated into the world of the Great Age of Piracy and became a colonel in a Navy branch. He awakened the Justice Instructor System.

From the start, he received One-Punch Man's special training course for himself, along with the Flowing Rock-Smashing Fist soldier training course.

By guiding his soldiers through the training and meeting the System's requirements, he could unlock new training courses.

Flowing Rock-Smashing Fist, two types of Haki, Sky Dance, Ki Blasts, the Eight Gates...

When the Summit War broke out, the Navy forces of Branch 188 became the most eye-catching fighters on the battlefield from the very start.

The Whitebeard Pirates' top commanders fought with all their might, yet couldn't break through the defenses of a group of Navy soldiers!

Rod: "Now! Enact justice!"

Whitebeard: "The Navy actually has a unit like this? One soldier is stronger than one of my commanders?"

Sengoku: "The Navy actually has such a powerful force! One branch alone is enough to match a Yonko, and I had no idea!"

Kizaru: "With Branch 188 here, I can relax and take it easy. What a relief!"
