The Grand Line: From the Start, I Summon Uchiha Madara

After transmigrating to the world of One Piece, Rogge obtains the Strongest Summoning System.

Uchiha Madara, Senju Hashirama, Kenpachi Zaraki, Aizen Sosuke…

As one powerful figure after another appears in the world, all the major powers take notice.

The Three Admirals: Which sea is the Hidden Leaf Village in? And why is its founder so terrifying?

Garp: What kind of title is a B-rank hero? Compared with that bald guy in front of me, I don’t think I deserve to be called the Fist!

Sengoku: What’s the deal with the Thirteen Court Guard Squads? The so-called Four Emperors don’t seem so frightening anymore.

The Five Elders: When did so many monsters suddenly appear in this world? Even more terrifying, they all seem to have the same leader!
