One Piece: I Can See Skill Proficiency, So I Became a Legend

On the boundless sea, Aokiji stopped a ship. After a fierce battle, he gave a helpless smile. "Hey, kid! Stop wasting your energy! I'm a Logia Devil Fruit user! You can't hit me!"

Before he could finish, a slash of sword energy flashed past, freezing the sea for miles. Aokiji, frozen solid, could only stare in disbelief. Did I eat a fake Ice-Ice Fruit?

In the second half of the Grand Line, Kizaru drawled, "Kid! You're saying you're faster than me? Now that's embarrassing!"

Before he could finish, a figure standing atop a flying sword shot thousands of miles away in the blink of an eye, leaving Kizaru dumbfounded in the wind.

Kaido: "I'm an Azure Dragon!"

Someone: "Sorry, but this sword of mine has another name: Dragonslayer!"

This is a story of a sword-and the making of a legend!

And, of course, a miracle in the world of One Piece.
