In short: After a brutal maritime massacre, a young boy named Julian is granted the combined power and lives of one hundred murdered slaves by a mysterious sea entity. Now, he must navigate a dangerous world to raise Diana, an infant girl destined to bring about the downfall of a powerful king.

Centuria, a Japanese web manga created by Tohru Kuramori, has been running on the Shōnen Jump+ platform since April 2024. The narrative begins with Julian, a boy who flees his life as a slave only to be caught in a horrific insurance fraud scheme. When the captain of his ship murders the captives, the resulting tragedy summons an eldritch entity. This supernatural force bestows upon Julian the strength and the remaining lifespans of the one hundred victims, including his mentor Mira, who had taught him the essence of humanity.

The story centers on Julian's commitment to raising Mira's daughter, Diana. Their journey is fraught with peril, as the kingdom's prophetess, Elstri, has foretold that the child will eventually trigger a great calamity. This prophecy places them in the crosshairs of the Torivian royal family and the Iris Stratum, an elite combat force composed of individuals with unique, supernatural gifts. Among these adversaries is Arkos, the nihilistic son of the Supreme Lord, who possesses powers similar to Julian's own.

The world of Centuria is defined by these 'gifted' individuals, whose abilities range from manipulating bone structure and physical weight to resurrecting the dead. Characters like the assassin Zana, who can reshape her own skeleton, and the healer Atoria, who sacrifices her own life force to mend others, populate this complex landscape. As of October 2026, the series has been compiled into ten volumes, chronicling the shifting alliances between former mercenaries, knights, and those caught in the shadow of the king's mysterious, veiled influence.

The conflict is further complicated by the political machinations of the Queen and the various commanders serving the throne. While Julian seeks a peaceful existence for Diana, he is constantly forced to confront those who view the child as a threat to the established order. The series explores themes of debt, survival, and the weight of inherited lives, as Julian carries the literal and metaphorical burden of the one hundred souls who died to ensure his survival.
