Navy Headquarters: I Take Wives and Concubines to Become the Strongest Admiral

Mo En transmigrates into the world of One Piece, where he becomes a Navy officer in the Grand Line and binds himself to the Strongest Partner System.

The more partners and wives he has, the stronger he becomes!

And so the Navy's most lecherous man is born!

Sengoku: "Although I can't stand his lecherous personality, the Navy can't do without his fighting strength."

Kizaru: "How scary. When it comes to marrying wives and taking concubines, this guy's a monster."

Akainu: "As long as he upholds absolute justice, what's so bad about having a few more partners?!"

The Five Elders: "What? He works harder when he takes a wife?! Quick! Go kidnap the princesses of the non-member nations!"

Mo En also discovers that the more famous his wives are in the original story, the greater the rewards he gets.

So... Nojiko, Kaya, Vivi, the Empress, and plenty more, you're all coming home with me!
