You Made Me an Intern, and I Terrified the Old Era?

[One Piece Fan Fiction] [Lighthearted Comedy] [Invincible Lead] [Crew Adventure] [Rumble-Rumble Fruit] [Old Era] [Snatching Opportunities] [Overwhelming Power]

After transmigrating to the old era of One Piece, Rayne discovers that he is on a sky island. From the start, he awakens naturally maxed-out Observation Haki and an unbelievably powerful knack for understanding things perfectly just by looking at them! On top of that, he uses his knowledge of the story to snatch the Logia among Logias: the Rumble-Rumble Fruit. As fate would have it, the Roger Pirates land on the island, and Rayne follows the principle that “it’s good to have a big tree to shelter under.” He talks Roger into letting him aboard as an “Rumble-Rumble guide” and joins as a trainee. He spends his days slacking off and playing the sly one on the ship, teasing young Shanks, swindling Buggy out of his secret stash, and secretly learning Rayleigh’s top-tier swordsmanship with Observation Haki. When he encounters legends of the old era like Rocks, the Golden Lion, and Garp, he transforms into a thunderous overlord, wielding a super electromagnetic cannon in one hand and a Thunder God armor in the other, overwhelming everyone with power and leaving the whole crowd stunned!

“Rayne, you call this a trainee?!” Watching an island get blasted apart by a single bolt of lightning, Roger falls into deep thought.
