An uncle who lives alone deep in the mountains.... Rika and Mana look forward to going there every year because it is a great nature. But the truth is that the uncle and mother have been paying their debts with their bodies without the young sisters' knowledge.... The older sister Kana is unable to read what is going on, but the uncle, as he is wont to do, taunts the younger sister Mana with obscene words. Wanting to somehow help her sister and her mother, Kana accepts her uncle's hopelessly disgusting proclivities. But gradually, the sickening feeling... gradually takes over Kana's body... more for herself than her sister... more for herself than her mother... more for herself than her sister... more for herself than her mother... more for herself than her mother... More than her sister, more than her mother....
