An independent collection of short stories — *Ultramarine Schooldays* highlights the color that evokes faithful memories, tenderness, and melancholy. These stories take place in Japan and in the West, in the past and in the present. They may involve a romance in the city, an energizing walk in the forest, the daily mundane life of a waitress working in a café, or a medieval intrigue; but what connects these stories are the powerful messages they deliver.
