Isami Maeda is Motoko's husband, Shigeki and Shihori's father, and Iwao's and Tomiko's son. He was a JA employee. He was seemingly uncaring towards Motoko as he never protected her from Iwao's and Tomiko's abuse. He was bitten by Iwao and forbid Motoko to call Toshio, but she did it anyway as she was fearing for Shigeki and Shihori. Toshio came to their house and examined him, but Isami refused to go to the clinic. Soon after Toshio left, Isami died. He was the second Maeda to die. Toshio later reflected on his refusal to be hospitalized.
