One Piece: Don't Worry, I'm a Doctor

Vir transmigrates into the world of One Piece and immediately finds himself hunted by Devil Fruit users. As an ordinary individual facing imminent danger, his survival seems unlikely until he activates the 'Traumatizing Miracle Doctor System'. This system promises random abilities by saving people while inflicting severe psychological trauma. Initially, Vir finds the system unhelpful, receiving only a basic antidote as a newbie gift. Despite this, Vir embarks on a legendary journey during the Marineford War. Witnessing critical injuries to Ace and Whitebeard, he boldly asserts they are "still treatable," much to the shock of onlookers. His unconventional approach to healing leads to bizarre situations, such as Aokiji questioning if he should eat a severed leg after Vir’s cryptic advice, and Whitebeard acknowledging Vir’s impressive "welding skills." Kizaru, tasked with capturing Vir, is astonished to discover the "doctor" possesses formidable Conqueror's Haki, forcing him to question Vir's true identity. A plea for help with facial paralysis further highlights the strange reality of Vir's abilities.
