[Hashida Mamoru] Kizuna (Kotori-kan 2) [Yxplore]

Mari-chan's mama lies dying in a hospital bed, and the director and his staff decide the little girl's body is the price of her treatment—filmed, surrounded, and ordered to moan loud enough to wake the very woman she's trying to save. Threatened that her mama will die if she stops, Mari endures every demand the men make of her small frame, while a mention of what her onee-chan does from below hints the darkness reaches beyond one sister. In the quiet aftermath, the girls cling to each other in tears and dream of bringing mama a present with a single 500-yen coin—a fragile thread of hope binding them together.
