Rossie is a member of the Todd Famiglia.
Rossie has a black mohawk and dark, narrow eyes. He wears a grey suit over a black shirt and a blue tie.
Rossie, when tracking down Fuuta, 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 Fuuta, but is goaded into fighting with his fellow chasers (Paulo and Enzo). The Todd Famiglia members, however, focus on a common goal and begin to advance on Fuuta 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.
- Rossie, as stated by Fuuta, is ranked 226th in intelligence out of the 86,202 mafioso Fuuta has seen.
