One Piece: The Strongest Summoner

After transmigrating into Pirate King, Luo Ya becomes a member of the Marines. He dislikes pirates, but hates the Celestial Dragons even more.

With the Strongest Summoning System, he can summon characters from every dimension and obtain their abilities.

"Come on, Ability Users! Let's fight out on the sea, and I'll show you what Water Release ninjutsu is!"

"Saber, use your holy sword to cut Doflamingo's strings. Yes, just like that."

"Boss Ban, I told you to take on Whitebeard, not to tear down Marine Headquarters."
