YU-NO: A girl who chants love at the bound of this world

Yu-no: A Girl Who Chants Love at the Bound of This World is a 1996 visual novel adventure game developed and published by ELF Corporation. It was originally released as an eroge for the NEC PC-98 Japanese home computer and later ported to the Sega Saturn and Microsoft Windows platforms without the sexual content. The story follows the protagonist travelling between parallel worlds to solve the mystery of his parents' disappearance. The game uses concepts from science fiction, physics, mathematics, philosophy, history and religion to construct its fictional universe. The "Auto Diverge Mapping System" (A.D.M.S.) that displays the branching parallel worlds and storylines as a tree helps the player navigate the game world. Yu-no was written and produced by Hiroyuki Kanno, and its FM-synth music soundtrack was composed by Ryu Umemoto, Ryu Takami and Kazuhiro Kanae, who had previously worked on C's Ware titles such as Eve Burst Error (1995). Yu-no was well-received and influential in Japan, where it revolutionized the visual novel industry and in turn had an impact on the manga and anime industries, inspiring numerous visual novel, manga and anime works. In 2017, 5pb. (Later Mages) developed and published a remake of the game for the PlayStation Vita and PlayStation 4. Spike Chunsoft released this version for PlayStation 4, Microsoft Windows, and Nintendo Switch in 2019. The game has also been adapted into a four-part hentai original video animation, a manga and novels, and a TV anime series by Feel that aired from April to October 2019. The TV anime series is licensed by Funimation and Crunchyroll outside Japan.
