faibles mais pourtant l'un des plus impulsif , il n'empêche , Leorio semble garder un passé trouble qui fait de lui une personne réservé . Sous ces air d'Arpagon, on distingue la vrai raison pour laquelle il veut participer à l'examen de Hunter : devenir docteur et ainsi pouvoir guérir des patients dont les maladies sont diagnostiquées comme incurable .
Much is unknown about Leorio. What we do know is that he once lost a close friend to a debilitating illness. Leorio feels deeply remorseful about not saving his friend, due to lack of money and knowledge in curing the illness. Thus, he aspires to become a doctor--one that not only cures the ill of their disease, but also waives the fee for the poor. In this light, his outwardly superficial reason to join the Hunter Exams in the pursuit of great wealth has a nobler justification--the money he gains is used not only to fund for his medical school fees, but also to pay for the medicine and other miscellaneous expenditures when treating the poor. Also, when asked on the boat about his reasons for becoming a hunter his immediate reply was to earn lots of money and becoming rich, which greatly annoyed Kurapica.
Leorio is not one who balks and retreats when faced against overwhelming odds in battle. A loyal, trustworthy ally who greatly values the ties of friendship, he acts like the 'big brother' of the group. However, his impulsive and brash nature has sometimes caused more trouble to people around him. Another flair he has is his ability to 'straight-talk' past any situation at hand.
Bargaining is one of his strengths, some say inherent nature, as he is able to haggle his way with shopkeepers and cut prices down to a unimaginable level.
