One Piece: This Prison Guard Just Wants to Watch the Fun

Good news: I've transmigrated. Bad news: danger lurks everywhere in this ocean. Good news: I have a golden finger that lets me learn other people's skills just by seeing them, and grow stronger and stronger? Bad news: everywhere I look, there are Devil Fruit users. There's no way to train these skills! Pupe Lann transmigrated into a prison guard at Impel Down and finally landed a steady job with regular hours and weekends off. No, no, no! If you've transmigrated into the world of One Piece, who would just go on working like an honest employee?

Doflamingo: "You absolutely mean that from the bottom of your heart."

Ace: "I'm skeptical about that."

Magellan: "My dear subordinate was stolen away just like that."

A prison guard at Impel Down in the early chapters, quits later on. Content warning: Ace and Rosinante are both alive.
