Rossi Valentia is a member of the Todd Famiglia.
Rossi has a black mohawk and dark, narrow eyes. He wears a grey suit over a black shirt and a blue tie.
Rossi, when tracking down Futa, stays outside Tsuna's house despite Gokudera, Yamamoto, and Haru's distraction. He later follows Tsuna to the park's playground as Tsuna tries to run away with Futa, but is goaded into fighting with his fellow chasers (Paulo Albani and Enzo Maccarinelli). The Todd Famiglia members, however, focus on a common goal and begin to advance on Futa and Tsuna, but Reborn shoots Tsuna with a Dying Will Bullet, allowing him to go into Dying Will Mode to defeat the Todd Famiglia members.
- Rossi, as stated by Futa, is ranked 226th in intelligence out of the 86,202 mafioso Futa has seen.
