Key Chapters
In 'Runaway Horses,' I bring back Shigekuni Honda, no longer the youthful observer of 'Spring Snow,' but a disciplined man schooled in law and logic. He has tried to distance himself from the passion that once consumed his friend Kiyoaki Matsugae, yet memory is never past—it lingers like a wound that never healed. Honda now serves as a judge, embodying the rational order of modern Japan. But one day, during a trip to see the son of Kiyoaki’s former tutor, he encounters a young man named Isao Iinuma whose features and mannerisms awaken a chilling familiarity.
The resemblance unsettles him; it feels less like coincidence and more like destiny. Honda’s pragmatic mind, trained to trust evidence, begins to unravel before the mystery of spiritual recurrence. In this moment, the metaphysical framework of 'The Sea of Fertility' deepens—the idea that souls recur through time, bearing the same passions under new disguises. To me, Honda represents the rational half of mankind, always wary yet irresistibly drawn toward the mystical cadence that underlies existence.
Honda’s fascination with Isao becomes both a moral question and a philosophical one. He wonders whether this youth carries within him Kiyoaki’s unfinished longing for purity, or whether he is simply projecting meaning onto resemblance. Through Honda’s eyes, I invite the reader into the tension between analysis and intuition, between observation and faith. He stands as the witness to universal recurrence: that the pursuit of purity, though reborn in new epochs, always hastens toward the same destruction.
Isao Iinuma grows up in the shadow of discipline. His father, the stern tutor of Kiyoaki, fills his son with notions of valor and sincerity drawn from the Bushidō code. Isao learns early that Japan’s modern society has betrayed the ethics of its warriors—abandoning sincerity for profit, replacing sacrifice with bureaucratic ambition. His life becomes a quest to embody the soul of the ancient samurai in a world that mistakes conformity for virtue.
In crafting Isao, I poured into him the purity of intention absent in Kiyoaki’s romantic indecision. Where Kiyoaki hesitated between love and honor, Isao chooses honor at any cost. He reads “The League of the Divine Wind,” an account of the Meiji Restoration’s patriots who sacrificed their lives to cleanse corruption, and in their blood he sees revelation. These are not historical ideals to him—they are eternal truths demanding resurrection. Thus, his youth becomes devotion; each action a ritual of sincerity.
Yet Isao’s intensity isolates him. He lives among shadows of glory that his society no longer understands. In him, modern Japan’s duality surfaces: industry and tradition, empire and individual. His mind burns with indignation at the complacency around him, and I allow that anger to shape his destiny. He believes purity demands destruction; that impurity must be cut away like gangrene. It is through Isao that I confront the fatal question: What happens when the love for a nation merges with the lust for perfection? He cannot distinguish redemption from annihilation, and therein lies his tragic nobility—the same nobility that will lead him to death.
