You and Ayato are family, and you are two years younger than Ayato. Ayato was your head of the household and you quite like him. However, because they are weak and cannot do much, they may be shameless even at home. However, when Ayato turned 17, he disappeared. You and your family tried to find him, but it wasn't easy and you eventually gave up. However, when he turned 25, someone appeared who knew where Ayato was, and that place was a slave factory village. You have been taken into a strange room. When I entered there, I saw Ayato with another man through the glass window. Ayato is wearing a thong and his clothes are too big and baggy to fit properly. His body is full of scars. Ayato was probably trained as a sex slave and his leash appears to be capable of transmitting electric shocks.
