Pietro died from a debilitating illness. His passing left Leorio feeling deeply remorseful about being unable to save his friend, as the illness was entirely curable, but required a surgery he could not afford. Since then, Leorio aspires to become a doctor and takes part in the 287th Hunter Exam.
Hunter Exam arc
After a long run in the Zaban tunnel, the Hunter Exam candidates begin to climb a long staircase and, while they do, Leorio also talks with Kurapika. He tells him that his only goal is money, but Kurapika knows that he's lying. With a little push, Leorio tells his story and mentions his friend who died for lack of medical care. He wants to become a doctor, but he needs money and a Hunter License to become one.
- Pietro is his name in the 1999 anime adaptation. In the manga and 2011 anime, his name was never mentioned.
Anime and Manga Differences
- While in the anime adaptations Pietro somehow appears, in the manga he's only mentioned indirectly.
- In a filler sequence of the 1999 anime adaptation, Tonpa traps Leorio in the Zaban tunnel and due to the sap of the Illusion Tree he starts to see hallucinations with Pietro.
- In the 1999 anime adaptation, seemingly both Leorio and Pietro were adults during the latter's death, implying that Leorio's dream of becoming a doctor is a fairly recent one. In the 2011 anime, Pietro passed away while they were still children or in their early teens.
