Kanon Hentai

Kanon is a Japanese visual novel developed by Key and originally released as an adult game on June 4, 1999, playable on a Microsoft Windows PC. An all ages version for the PC was released in January 2000, and was later ported to the Dreamcast, PlayStation 2, and PlayStation Portable. The Kanon Standard Edition was released for the PC as an adult version in November 2004 and an all ages version in January 2005. Both Standard Editions are playable as a DVD-ROM and incorporate the extra graphics added to the earlier all ages version of the game, added support for Windows 2000/XP, and other technical changes such as more save slots. The gameplay in Kanon follows a linear plot line, which offers pre-determined scenarios and courses of interaction, and focuses on the appeal of the five female main characters.

There are several important locations featured in the Kanon story, though the location names are seldom mentioned explicitly in Key's works. The time of year the story occurs in is during winter, and since it often snows periodically over the course of the entire story, the city is always presented covered in a layer of snow. The shopping district is featured throughout the story when the characters go into town, and especially whenever Ayu appears in the early story. The high school where Yuichi and the other main characters attend, including the school grounds, is shown predominantly in Shiori's and Mai's stories, and is otherwise a general setting where Yuichi interacts with other characters.

There are recurring themes that appear throughout the story. A music theme is present, as the episode titles from the 2006–2007 anime have parts in their titles related to music, such as overture and introit. Miracles play a large part in the story; Kanon's plot line and characters are influenced by various instances where miracles occur. The act of promising and keeping promises is found throughout the story. Yuichi eventually makes important promises to the five main girls while at the same time fulfilling past promises he had made with four of them when he used to visit the city as a kid.

One of the motifs in the story is amnesia, or memory loss; three of the main characters—Yuichi, Ayu and Makoto—suffer from amnesia in varying degrees; this is used as a plot device to advance the story. Another motif deals with the favorite foods of the five main heroines. Newtype USA stated in an article on Kanon that, "it's when the characters are eating something really tasty that they seem most beautiful and alive," despite the somber setting and overall tone of the series. These five foods of choice are: taiyaki (Ayu), strawberries (Nayuki), nikuman (Makoto), ice cream (Shiori), and gyudon (Mai).
