One Piece: Shadow monarch? I'm Just Logistics! Novel

Reiner claims he's not an ambitious person—he simply wants to travel the world with the Straw Hat crew while collecting the souls of the dead. From enemies like Kuro and Arlong to Crocodile and Shiki, his collection grows increasingly bizarre. Demons with goat horns and snake tails he can rationalize, but a Chainsaw Demon? And where did this Sukuna even come from? At the Summit War, Sengoku and the Three Admirals are stunned to discover that the incredibly powerful individuals surrounding Reiner are actually undead beings under his control. They struggle to comprehend how someone they viewed as merely a handyman performing chores for the Straw Hats could command such strength. When confronted about this seemingly impossible feat, Reiner grows irritated, insisting that performing every conceivable job absolutely qualifies as logistics. The story follows the Straw Hats' journey with original plot elements, featuring a protagonist who is neither naively righteous nor corrupted by darkness.
