This novel is about the endless chatters of the members, full of parodies from various other works such as "The Melancholy of Haruhi Suzumiya", "Dragon Ball" etc.<br><br>
The series was originally planned to be titled as "Hekiyou Academy Student Council's Minutes (&#30887;&#38525;&#23398;&#22290;&#29983;&#24466;&#20250;&#35696;&#20107;&#37682;, Hekiyou Gakuen Seitokai Gijiroku), but because of the length, the title of the first volume "Seitokai no Ichizon" was chosen to refer to the whole series. It is also called "Seitokai Series" by some.
