In One Piece, I Get Stronger by Making Friends

He transmigrates into One Piece and gains the Strongest Bonds System.

By forming bonds with characters from the story, he can obtain their strongest talents and activate buffs that benefit both sides.

A master-disciple bond with Koshiro, a childhood-friend bond with Kuina, a bond of brotherhood and friendship with Zoro...

The bonds between the three greatest swordsmanship prodigies combine to grant him an SSS-rank swordsmanship talent, with a 1600% bonus to swordsmanship training!

Building on this foundation, he forms all kinds of bonds throughout the world of One Piece.

And so, an unbeatable being who excels in every way is born into the world of pirates!

"He is the undisputed World's Strongest!" Whitebeard exclaimed.

"At last, I have a worthy opponent!" Mihawk said, his fighting spirit ablaze.

Garp picked his nose. "In ten years, this kid will become Fleet Admiral!"

A few years later, an enraged Sengoku leaped up and punched Garp, knocking his head sideways. "You call this guy a Fleet Admiral?!"
