Cristiano leads the Padania Republic Faction, a terrorist organization active in Italy. He discovered the young assassin Pinocchio hidden during a mission, subsequently raising him. Cristiano serves as both mentor and father figure to Pinocchio, training him to execute assassinations for their faction.

He spearheads the planning for a major terrorist attack on the Strait of Messina Bridge. Cristiano coordinates this operation with fellow faction members Flanca and Franco, assigning Pinocchio to assist them with the bombing. During planning, Flanca expresses surprise at Pinocchio's social awkwardness and lack of basic knowledge, such as failing to identify her car model.

When intelligence reveals authorities are preparing to arrest Cristiano as law enforcement closes in, he urgently consults Flanca, Franco, and Pinocchio. They discuss advancing their bombing plot despite heightened security around the bridge. Cristiano's leadership within the faction and his unique relationship with Pinocchio define his role.
