The Fierce Golden Country, Kinjirou Ninomiya

While surveying the whole of Japan, Ino Tadataka happened to come across a boy named Ninomiya Kinjiro, who was reading a book while carrying firewood on his back. The Kinjiro family had lost their father and were living in poverty, but they also lost their mother, and the siblings were left in the care of different relatives. Kinjiro vowed to come and get them.
