Holy Roman Empire is portrayed as a petite blond child wearing a black hat and cloak, later reimagined as a teenager in a white Teutonic Knight-inspired uniform. His height, humorously quantified as “7 apples and a tangerine,” positions him slightly taller than Chibitalia. Early designs feature dark blue or black eyes and attire, while his anime iteration adopts rounder, brighter eyes and gray breeches.

As Germania’s grandson, he exhibits fierce determination despite frail health. His central goal revolves around persuading Chibitalia—whom he perceives as a girl—to join his empire, fueling persistent but unreciprocated affection. This dynamic culminates in a poignant farewell where Chibitalia gifts him an intimate token: her panties in the manga, altered to a deck brush in the anime. They pledge reunion post–Thirty Years’ War, though their paths never cross again, with the creator ambiguously alluding to a potential “happy ending.”

Under Austria’s strict mentorship, he develops sharp intellectual prowess but lacks artistic skill. His temperament blends irritability with sporadic kindness. The Thirty Years’ War leads to his presumed demise, later confirmed in a deleted scene where France informs an adult Italy of his fate.

In *Paint it, White!*, he surfaces in a dreamlike riverside encounter with Chibitalia, echoing their unresolved bond. A chibi cameo during the film’s finale depicts him seated beside her on Poland’s pony, symbolizing their enduring connection in fan-centric narratives.

Historical contradictions obscure his lineage, alternately cited as Germania’s grandson or son. His potential identity as Germany remains deliberately ambiguous, with the creator withholding clarification on whether they share existence or diverge as separate entities—an intentional enigma enriching his allegorical role.
