Because the entire building was like a fancy five story hotel itself, it wasn't too much of a problem for almost every student within that building to hear about the commotion that both Yuda and Sato caused. The fight was below at a small park that was inside in the middle of the entire building, because the two troublemakers were lucky enough to stay at the first floor. Because they were at the first floor, it was easy for them to be as wild as they wanted to, since they didn't have to be careful about falling from the building while they went at it with each other.
