Kanno Hiroyuki, writer of EVE, DESIRE, YU-NO, Mystereet and other games passed away due to a stroke on December 19.
With both him and Umemoto Ryuu (who passed away earlier this year) now gone, YU-NO stands out even more clearly as an unrepeatable feat in the eroge world- neither of the creators that evisaged this eroge and made it happen are still around.
Without Kanno, modern eroge would not be what it is today.
