The next day, the news reports the event of a violent homicide in the park where Koichi committed the murder in his dream.

Kizuato is known for being historically notable and defining the visual novel genre. It has been described as similar to Shizuku, with themes of bloodshed, violence, and humiliation, with a "dark narrative". Some have argued that having character's hair spring up by antennae was popularized by the game, later becoming standard in games and anime. Kizuato was described as eroge but notable for combining the sound novels form with "erotic content". The visual novel was also mentioned by Konoha Akisato, the protagonist of 16bit Sensation: Another Layer, with the novel as an important part of setting the historical context for the anime's story.
