It puts a pretty high school girl in the frame and then makes you watch her work, and the whiplash between those two facts is the entire point. Tamaki Suzuhara isn't a victim who stumbles into the organ trade, she signs up with the traffickers, harvests the people they abduct, and does it because someone she loves is missing and this is the fastest road to finding them. The show treats bodies as inventory, which is exactly how the underground market treats them, and it doesn't blink when the supply chain runs past Japan's borders into China. Twenty ONA episodes, no prestige budget, no attempt to make any of it pretty. That's why the people who found it keep pushing it on everyone else: it's mean, it's cheap, and it never once apologizes for what Tamaki is willing to become.
Tamaki Suzuhara is a beautiful, enigmatic high school girl looking for someone who matters deeply to her and who has disappeared. In Japan, soaring demand for transplant organs has given rise to underground groups that abduct and kill people to sell their organs, with surgeons joining in and the trade spreading as far as China. Tamaki becomes part of one of these illegal networks, which seizes people it has judged on moral grounds and surgically removes their organs. Her path turns bloody and leaves her facing a moral dilemma as she keeps searching. Gift± is a 2018 horror ONA running 20 episodes.
