Kanon (visual novel)
Most of "Kanon"s development staff originally worked for the visual novel publisher Nexton under the brand Tactics. After the release of the brand's third game "", most of Tactics' staff left Nexton to pursue work in another publishing company where they could have the freedom to produce their next game. Itaru Hinoue, who had previously worked at VisualArt's once before, introduced Key's founding members to the president of VisualArt's, Takahiro Baba. Baba gave the developers the freedom they desired, and they officially transferred to VisualArt's where they formed Key on July 21, 1998 and started production on "Kanon". The planning for the visual novel was headed by Naoki Hisaya who was also one of two scenario writers with Jun Maeda. Hisaya wrote the scenarios for Ayu, Nayuki and Shiori, while Maeda wrote the routes for Makoto and Mai. Art direction was headed by Key's artist Itaru Hinoue who worked on the character design and computer graphics. Further computer graphics were split between three people—Dinn, Miracle Mikipon, Shinory—and background art was provided by Torino. The music in the game was composed by OdiakeS, Shinji Orito and Jun Maeda. "Kanon" was the first and last visual novel developed by Key that two of the main staff—Naoki Hisaya, and OdiakeS—worked on before pursuing a similar line of work in other visual novel studios.
Kanon (visual novel)
In the adult versions of the game, there are scenes with sexual CGs depicting Yuichi and a given heroine having sex. Later, Key released versions of "Kanon" without the erotic content. The versions that include the adult content have one explicit sex scene in each of the five main story routes, in addition to one fantasy scene. Outside of these, there are two scenes with nudity. Yūichi Suzumoto, a scenario writer who worked on later Key titles, commented that the sex scenes in "Kanon" are very self-contained, and can be easily removed without altering the story. Maeda remarked that the sex scenes were not written with reproduction in mind.
