Hitori is a historical-fiction novel set in 17th-century Japan, amidst the final major battle of the Sengoku Jidai—the Shimabara Rebellion. It follows a wandering samurai haunted by his past. Drifting through Nagasaki, Hitori is numb to the world—until he crosses paths with Ame, a widowed noblewoman accused of sheltering fugitive Christians. When forced to choose between indifference and action, he intervenes, setting him on a path that entangles him with the Christian Rebellion and the final battle of a century-long era of war. Hitori blends historical intrigue with poetic introspection. It is a tale of loss, honor, and the bonds that endure beyond despair.
