Story Overview
The manga moves across billions of years of human and civilizational history, following recurring figures — Plato, Siddhartha, a woman named Orionae, a mysterious boy — whose appearances across different epochs suggest they are something more than ordinary historical persons.
The connecting thread is a question: who created this universe, and what is the relationship between the creator and the created? As civilizations rise and fall, the figures pursuing this question approach an answer that the manga renders with unusual honesty — the truth, when they reach it, is neither comforting nor reassuring.
Hagio's adaptation compresses Mitsuse's sprawling novel into two volumes without losing its scope or its philosophical substance. The compression is itself an artistic achievement — knowing what to keep and what to let go.
Characters
The recurring figures: Each historical person appears as themselves but also as something larger — representatives of a type of consciousness that persists across time. Plato as philosopher, Siddhartha as seeker, Orionae as something that the narrative doesn't fully categorize.
The boy: A figure whose identity becomes clear only gradually — and whose nature, once understood, reframes everything that preceded it.
Art Style
Moto Hagio's art in this work has a spaciousness that matches the cosmic scope — figures drawn with psychological precision against backgrounds that suggest the vastness of time. The historical settings are sketched with suggestive accuracy rather than archaeological detail, keeping the focus on the figures and their encounter with the central question.
Cultural Context
The original novel by Ryu Mitsuse was published in 1973 and is considered one of the masterpieces of Japanese science fiction. Hagio's manga adaptation appeared in Shojo Comic in 1977, reaching an audience for whom the novel might have been inaccessible. The combination of Mitsuse's ideas and Hagio's visual storytelling produced something that transcends both.
What I Love About It
I love the ending's honesty.
Science fiction that asks cosmic questions — who are we, who made us, what is our relationship to creation — usually provides cosmic comfort: the universe is knowable, the creator is benevolent, the pattern makes sense. Hyakuoku no Hiru to Senoku no Yoru does not provide comfort. It provides an answer, and the answer requires something of the reader that comfort would not.
This is rarer than it sounds. To reach a genuine conclusion rather than a consolation is a form of artistic courage.
What English-Speaking Fans Say
Not known in English-speaking markets. Among readers of literary science fiction manga and Moto Hagio's complete work, this is considered one of her greatest achievements — a work that demonstrates what the manga medium can do when it aspires to the ambition of the best literary SF.
Memorable Scene ⚠️ Spoiler Warning
The moment when the recurring figures reach their destination — the source of the question they have been pursuing across billions of years — and find something that the narrative has prepared you for without preparing you for. The revelation changes nothing about the physical universe. It changes everything about how you understand everything that preceded it.

Is Hyakuoku no Hiru to Senoku no Yoru Worth Reading?
For readers of serious science fiction and Moto Hagio's work, absolutely — this is a landmark achievement, and the two-volume length means the commitment is minimal relative to the experience.
