Yuichi is a self-contained, hardworking young man whose life runs parallel to—but separate from—the Takaras and Nakamuras. He comes from a family marked by displacement and economic struggle, and he responds with quiet discipline and an understated sense of responsibility.
Yuichi rarely volunteers his emotions, but he feels them deeply. He cares for his own family circle, works steadily, and shoulders burdens without complaint. He is observant, reliable, and respectful.
