On the day Luffy set out to sea, he already owed me ten islands.
Garp thinks he can welch on the debt?
Not a chance. I have the Marines hero’s iron dog-head badge in my hands. He’ll acknowledge this debt whether he wants to or not.
The White Mask is stirring up trouble behind the scenes?
One kick, and the Seventh Treasury goes straight to the bottom, without a scrap left behind.
As for that masked woman shrouded in black cloth, I can mend her shattered hand, and even save her life when she’s on the brink of death. But if anyone dares make her shed even one more drop of blood...
Sorry, I’m Zhang Daoling, a debt collector for gods and ghosts.
In all the world, anyone who owes a debt must repay it, even the Pirate King!

To be honest, I read more than ten chapters and didn't understand the setting.
