The Delivery Man is the one who delivers the packages throughout Namimori. His truck seems to always get dented whenever Tsuna, in Dying Will Mode, runs around through town and hits his truck. It seems he is very proud of his job and has delivered every delivery package he has on time, willing to risk his life to do so. He's been a delivery man for 15 years.
The delivery man is seen briefly multiple times shouting at Tsuna to pay for damaging his delivery truck. His major appearance was when Tsuna thought he killed Moretti when in fact it was just Moretti's ability, Addio.
