One Piece: Me, the One-Punch Admiral

[Momonosuke must die + invincible One-Punch Man + everyone overestimates him + Marines + martial arts] This Marine is clearly strong, yet he loves slacking off! Marine Captain Edward sees himself as an utterly ordinary office worker. His life's ambition is to slack off at work and clock out on time. He thought his life would pass by in an entirely unremarkable fashion. Who knew that one day he would unexpectedly awaken the Ancient Desolate Saint Physique, the strongest human battle constitution in the world of Shrouding the Heavens? "Well, punching each of the Four Emperors into oblivion is just how it is, I guess~" Also known as: "I Awakened the Ancient Desolate Saint Physique from the Start" and "This Marine Is Clearly Strong, Yet He Loves Slacking Off" P.S. This is an invincible-power fantasy with a focus on feel-good wish fulfillment, but the characters' intelligence and the story's logic should mostly hold up.
