Seitokai Yakuindomo Whistle

Seitokai Yakuindomo Whistle, do you mean someone who blew the whistle when Shino was announcing the school rules?

Exactly! And it is Suzu. Almost in every segment of the reading school rules, Suzu always comes up with blowing whistles, and Aria who beating the drums.

Actually there is no definite purpose, just as the encouragement and the attention to you to listen the school rules carefully.
