Miya-chan was a former member of the Japanese national team in the 48kg judo class. After retiring from judo, she started working for a regular company, but perhaps due to the backlash of her rigorous training, her body was not satisfied with just working normally, and her sexual desire was unstoppable, so she met men on dating apps and other such. There, she got hooked on the oxygen deprivation play that she had loved since her judo days! When she posted a video of this on the internet, she received a DM from the doujinshi AV director Iceman saying, "I'll take you to heaven..."! She couldn't help but be curious, so she arranged to meet up.
