Game Content
Yuto Yuki lives with his well-cared-for younger sister, Ayaka, due to their parents' work reasons.
Although he is often scolded by Ayaka, he still leads a peaceful daily student life,
But in places he doesn't know about, this peace has already begun to crumble.
One day, after returning home from school, he finds an email on his computer.
The email contains a video, and when played, the screen shows his sister, who had breakfast with him that morning, being trained on her buttocks.
Unable to believe the content of the video, Yuto sees Ayaka return home with her expression and behavior as usual,
and after tentatively asking her, she seems unaware, so he thinks the video is just someone's prank.
However, the next day.
Another email arrives, titled "Current Situation",
with an attachment of a photo of Ayaka suspended by ropes and her nipples clamped with clothespins.
Facing the humiliating state of his sister in the photo, Yuto's body involuntarily reacts,
and his heart is filled with both excitement and anger, but he still decides to use the clues in the photo to go find his sister!
