In Kaze Hikaru
Inoue Rintaro, later Okita Rintaro as he is adopted into the Okita household, is the third son of a goshi family; a family that received bushi treatment but was involved in farm work.

After Okita Katsujiro died, he left the family in a precarious state. Though they now had a male heir, the family had lost its sole source of income. Thus, Nao decided to move the family back to her hometown, though she refused any help from her parents. Though they were optimistic and dedicated, the family was soon close to starvation.

When Nao's oldest daughter was 14, Inoue proposed, knowing full well the dire circumstances the family was in. The dowry would be enough to help support the family, but Nao refused as her daughter was very young. Mitsu, however, disagreed and accepted the offer.

Though it was expected that his presence would help the family, unfortunately Inoue was a lousy bargainer and the family remained in poverty. Nevertheless, he was well-liked, described as a kind and gentle man. He cared deeply for the family, especially his wife Mitsu, and even arranged for her younger sister, Okita Kin, to wed a noble Edo lord.
