The incredible second supplement for Schoolgirl RPG gives you 14 pages of new material (including the cover and introduction, but you know what I mean).

• Asides: These new rules add "asides" to the game, little interludes where players compete to be funny.
  
• Even More Random Event Tables: Two more random event tables: Everyday Life (guess what anime it's based on) and Summer Break at the Beach House.
  
• Items: A d66 table of special items with rules attached, including the Aperture Gun, Diabolic Hat, Sonic Screwdriver, and Vorpal Bunny.
  
• Teacher Rules: Rules for rolling up teacher characters, for use as either PCs or NPCs.
