A comedic twist on the "rankings trope" found in anime, pinning Han, a 14-year-old boy who becomes the #1 greatest swordsman by accident, against the entire world. Han finds himself encountering some of the strongest swordsmen in history. "With the whole world literally trying to kill you, what else can you do except learn how to fight against it?" Swordsmen, most are as passionate about the art as they are dangerous. Others use the blade for less honorable reasons. Some serve the military by the king's decree, and very few, that I've seen in my lifetime, could level mountains but decide to sheathe their blade for a greater purpose. How would you know who is the strongest, the greatest among these master swordsmen? It's not by battle scars or the technique they use. Not by their merit, nor physical strength, but by a symbol on their body—a tattoo that will appear as number "#1," "#2," and so on. There are #100 of these numbered swordsmen, all vying for the #1 rank. Fame, glory, money, women, respect—this is what the #1 has. Han, an orphan paired with an unlikely group that comes from similar backgrounds, finds himself being hunted by groups of bounty hunters, imperial soldiers, master swordsmen, and even random villagers. The fast-paced adventure will follow the group as they embark on the journey of their lifetimes. To protect Han, the supposed "#1 Greatest Swordsman to ever live."
