Konan High was the undisputed volleyball king in Japan. It wasn't just a talk, but there was also a lot of data to back that up. For example, in their own prefecture, Tokyo, only Matsukita High was able to steal a set from them, and the last time it happened was two years ago. Yeah, you hear it right. Two years ago! During the previous two years, they had never lost a single set against any team from Tokyo, which showed how dominant they were on the court.
As for the other team, let alone a set, managing to reach the 10 points in one set would basically be treated as a miracle or a big upset by the others. They – Konan High – usually managed to crush everything in front of them in a dominant style, never allowing their opponent to score two-digit points in a set. This legend also made any weaker team tremble in fear when they were going to face them, making it easier for Konan to kill them.
