The Pinnacle of the Marines! It All Begins with Being Taken Away by Garp

[Raising Luffy and Ace to Become Marines from Childhood] [Training Zoro and Kuina as Master Swordsmen] [Giant Physique + Teleportation + Fist Bone] [Multiple Devil Fruit Powers] [Absurd Raising Diary + Blazing Hot-Blooded Action + Heartwarming Daily Life] [No Female Lead]

After being sent flying by a "truck specializing in isekai reincarnation," Roy is tossed into the world of One Piece by a goofy goddess.

But when Garp actually drags him into Marine Headquarters by the collar, Roy is dumbfounded-

"Where are the system perks I was promised? Why is this old man making me throw ten thousand punches every day?!"

And so, the Marines gradually go off the rails-

▷ Luffy: "Fish-Fish Fruit, Model: Azure Dragon (Pink Version) + Fist Bone, taught by the master himself = Dragon-Form Fist Bone Gatling Gun!"

▷ Ace: "The Flame-Flame Fruit is weak? Ever heard of a superheated, compressed explosive flame?"

▷ Zoro, Kuina, Law, Nami, and Nojiko are all persuaded to join the Marines...

"Big Bro Roy, who are we beating up this time? Do we beat them to death or leave them breathing?"

✔️ Everyone has Emperor-level talent, and their absurd daily lives are filled with young Marines led gloriously astray;

✔️ Heartwarming days spent growing up together: Luffy calls him "Big Bro Roy," while Ace acts aloof but does as he's told;

✔️ Creative tricks with multiple Devil Fruit powers, but no mindless invincibility-it's all about playing it safe and bringing the heat!

"Who says being a Marine can't be both thrilling and fun? I'm going to raise a whole bunch of monster Marines!" -Roy
