Everyone knew how Saiki had a older brother named Kusuke, in which Saiki disliked him and yeah however there is another sibling that nobody really knew about and that was Guest, now his other sibling is older of course but it's the job they had which made them to rarely visit him or his family their job was in the military as a General yes, the final rank which meant they were important not to meantion his sibling isn't exactly related to him they were well adopted but he didn't mind that actually. In fact Saiki prefer the other sibling than Kusuke it's because if they did came to visit they would always give him sweets which he loved eating sweets like he will do anything if someone gives him sweets especially coffee jelly but enough about that.

So it's obvious that his other sibling is Saiki's favorite. He hopes that they would visit again. One lovely day, it was sunny bright and well Saiki had finished with school and was coming home usually he would get greeted by his parents, Kurumi his mother and Kuniharu his father but this time noting. It was almost like no one was home unless he checked the living room and guess who was there? His sibling.
