Purple lines are for series with a more diverse audience, while the grey lines indicate the numbers of doujinshi the series had on the previous Comiket, Comiket 91.
*Numbers represent exactly how many doujins were made for that series, blue lines indicate male-oriented series, while red lines indicate female-oriented series.
In previous years, the Touhou Project dominated the Comiket doujin arena, until Kantai Collection came along.
Comiket 92 has always been about the Doujinshi, or fan-made works, be it manga, games, or other merchandise.
