Hi no Tori, or Phoenix, is an anthology series that explores the cyclical nature of humanity's ambitions and follies throughout history.
Each arc focuses on a different era, from the dawn of civilization to a far-flung future, with the immortal Phoenix acting as a silent observer.
The overarching theme revolves around humanity's relentless pursuit of power, justice, and freedom, and the consequences of these desires across various time periods.
Each story, while self-contained, contributes to a larger tapestry illustrating the recurring patterns of human behavior and the enduring impact of our choices.
Essentially, it's a philosophical exploration of human nature as witnessed by an immortal being throughout time.
