I'm a Lazy Navy Officer, and My Father-in-Law Is Red-Haired Shanks

Shen An transmigrates into the world of One Piece with a Sword Saint System and becomes a Marine.

He doesn't practice swordsmanship, only sword intent.

The body Shen An transmigrated into seems to hide a huge secret. He was born with Conqueror's Haki!

He also mysteriously has no memories from before the age of five, and Garp exiles him to a remote branch base for fifteen years.

One day, Garp, who hasn't paid Shen An any attention for fifteen years, suddenly shows up and says,

"Shen An, you have a fiancee.

Her name is Uta. She's a songstress!

Go marry her!"

Arranged marriages are a terrible idea!

Shen An firmly refuses, then sets off to find his fiancee!

During his journey, he meets a great swordsman who's pretty powerful.

Shen An says, "Of all the sword intent under heaven, I claim eight tenths for myself. You and Red-Hair get one tenth, and everyone else shares the last tenth!"

At the wedding,

a somewhat famous red-haired man with one arm suddenly appears and says to Shen An,

"I'm Uta's dad!"

Shen An: "There's no need to go that far. Don't say that!"

"I really am Uta's dad!"

"All right, I can see that now!"
