Apathy belongs to the investigation-visual-novel genre so common in the Japanese DS catalog: it sets the action at the fictional Narukami Gakuen high school and its "urban legend detective bureau" ("toshi densetsu tantei kyoku"), where the player progresses through text, dialogue choices, and solving small mysteries tied to Japanese school folklore.
With no release outside Japan and little documentation available in other languages, it's one of those titles that today only show up in databases specialized in the console's domestic catalog.
