What if the legendary Santa Claus was actually a genetic lineage in a dystopian future?
In short: In a 2080 Japan gripped by a declining birth rate, the state controls every aspect of childhood. But when a middle schooler discovers he is a descendant of Santa Claus, a forgotten legend begins to transform a rigid society.
Paru Itagaki’s manga series, Sanda, presents a chilling vision of 2080 Japan. To combat a rapidly declining birth rate, the government has implemented extreme control policies for minors. These include arranging marriage partners from infancy, preventing children from sleeping to slow their development, and even mandating separate toilet use from adults. In this era, the figure of Santa Claus has been relegated to myth or ancient legend, as his presence was long sealed away due to a curse. In this dystopian landscape, the social hierarchy is inverted, granting young people a higher status than the adult population. This era is marked by a deep sense of loss, as the character Ichie Ono has gone missing, prompting the central investigation.
The narrative shifts when the seal on Kazushige Sanda is broken by his classmate, Shiori Fuyumlaru. Sanda discovers a startling biological reality: he is a descendant of the Santa Claus lineage. Donning red garments allows him to shift into an alternative persona possessing immense power, immunity to flames, and ski-like feet. A more sinister 'Black Santa' state exists for penalising the bad, yet returning to his usual state requires eating 'Bratty Beans'. This transformation is triggered specifically when Sanda wears any red clothing, even if it is stained with blood. His secondary identity also possesses the unique ability to sense when someone is lying.
Beyond the supernatural elements, the series explores profound themes of maturation and systemic tension. Itagaki uses the protagonist's struggle to balance adolescent life with his new powers to reflect on the transition from childhood to adulthood. Critics have noted that the work moves away from the anthropomorphic metaphors of Itagaki's previous work, Beastars, to confront societal issues—such as the contradiction between state protection and individual autonomy—directly through human characters. The series also examines the complexities of identity, particularly through Fuyumura, who struggles with a sudden, dramatic growth spurt. Furthermore, the story features a 92-year-old cyborg headmaster who uses medical implants to maintain a youthful appearance.
