Japanese media website CUPO conducted a survey of all of the light novels published in Japan from April of 2015 until March of 2016 to determine which light novel deserves the honor of possessing the “Longest Light Novel Title of 2015”. The rules of the survey were simple: count all the characters in the light novel’s title and subtitle. Volume numbers were excluded, and when a special edition version of the light novel exists (with extra goodies such as drama CDs/OVAs/Specials packed in), only the title of the standard edition was used to determine the total character count.
First place went to Sigsawa Keiichi and Kuroboshi Kouhaku’s Sword Art Online Alternative Gun Gale Online IV 3rd Squad Jam Betrayers’ Choice (ソードアート・オンライン オルタナティブ ガンゲイル・オンラインIV ―サード・スクワッド・ジャム ビトレイヤーズ・チョイス〈上〉―) with a total of 57 katakana characters.
Second place went to Ryo Iwanami and Munyuu’s Yuusha ga Shuraba Sugite Sekai wo Sukkuteru Baai Janai Maou no Noroi de Heroine-tachi wo Douji Kouryaku Shinakereba Narimasen (勇者が修羅場すぎて世界を救ってる場合じゃない 魔王の呪いでヒロインたちを同時攻略しなければなりません) with a total of 47 characters in kanji, katakana, and hiragana.
Meanwhile Kenta Dairaku and Takashi Konno’s Koko wa Isekai Konbini Daemon Eleven – Okyakusama, Kaifuku Maho o Kakenagara no Tachiyomi wa Go Enryo Kudasai! (ここは異世界コンビニ デモン・イレブン お客様、回復魔法をかけながらの立ち読みはご遠慮下さい!), with Sigsawa Keiichi and Kuroboshi Kouhaku’s Sword Art Online Alternative Gun Gale Online I Squad Jam (ソードアート・オンライン オルタナティブ ガンゲイル・オンラインI ―スクワッド・ジャム―) come in at a total of 46 characters each at third place.
