One Piece: I'm Almost Dead of Old Age, and the System Finally Shows Up!

After entering the world of Pirate King, Ron discovers that the System's progress bar is stuck. For a full hundred years, the System has been nothing but a decoration, refusing to come online no matter what. Fortunately, he knows the story inside out and, thanks to his foresight, has become a living relic of the Marines. He once picked up the snot-nosed Garp and raised him himself, was sworn brothers with Kong, trained Sengoku, Zephyr, and Tsuru, and now even has his great-grandson Luffy practicing his punches under him.

At a hundred years old, Ron finally can't withstand the effects of age and decides to accept his fate. That's when the System lights up, the progress bar fills, and a window pops up with its first mission: "Host, get promoted to Marine Admiral within one year." Ron immediately loses it. "I'm already this old, and you're asking me to become an admiral?"

Still, a mission is a mission. When a group of pirates with bounties totaling tens of millions appears in the Turbine Waters of the East Blue, he still heads out to sea with a wine gourd in hand. Two punches take down the captain, and one kick knocks out the executioner Sims. He doesn't use Haki at all, clearing an entire ship with nothing but eighty years of old-fashioned punches. Meanwhile, Sengoku, far away in Marineford, clutches the Den Den Mushi that won't connect and is already calling Garp and Tsuru in the middle of the night: the old man is causing trouble again. Hurry up and stop him.
