A Mo, a young man from Windmill Village, traveled through time. Others awakened to god-level fruits such as Shaoshuo and Rubber. He picked up a "waste fruit" with red and black lines and a touch like a bath towel - it could only peel off impurities and could not even pierce a tree.
Ridiculed by Ace as "it's just digging sand" and dismissed by Luffy as "not as fun as rubber", Ah Mo has come up with new tricks: "maintaining" the red-haired famous sword to remove rust, making the bamboo sword sharp, using the peeling blade to harden the gravel fruit, and "removing the toughness" of the quick-cut fruit's steel!
From a small village in the East China Sea to Alabasta, he carried a rusty dagger, teamed up with Luffy to explore the Grand Line, used his "scrubbing" ability to forcefully defeat the Shichibukai, and helped the giant repair a century-old axe. Even Robin looked at him with strange abilities.
Who said that the fruit of waste wood cannot be used as a hanging fruit? Let's watch Ah Mo use this "All Things Maintenance Technique" to slash his way to the throne of the world's greatest swordsman!
