Shinyaku Toaru Majutsu no Index: Breaking the Appetite Limit (新約 とある魔術の禁書目録 食欲の限界突破,Shinyaku Toaru Majutsu no Indekkusu: Shokuyoku no Genkai Toppa?) is a story written by Kamachi Kazuma that was published on one of the Dengeki Story Trading Cards 2012. This trading card was released during the "Dengeki Bunko Bucchigiri! Breaking Limits!! Fair" (電撃文庫ぶっちぎり!限界突破!!フェア,"Dengeki Bunko Bucchigiri! Breaking Limits!! Fair"?) that celebrated the 20th anniversary of ASCII Media Works. Those who bought a light novel published by Dengeki Bunko with a special paper strip wrapping from specific bookshops would be randomly given a story trading card. The specific Shinyaku Toaru Majutsu no Index could be collected from the October activity. It is later included in Super! Dengeki Bunko.
