A visual novel revolving around Sayori's original cat girl characters. Localized to English by Sekai Project.
So far, there are five "episodes" in the series:
Episode 0, which is counter-intuitively the second novel released, is a short "fandisk" that takes place before the events of episode 1, and gives the player character's sister a much larger role. It's also somewhat of a showcase of new features not present in the first game, which include the ability to directly interact with the cast by clicking on them.
Episode 1, the first novel released, centers on the characters Chocola and Vanilla, whom the main character lives with, sleeps with and eventually has sex with. While Chocola and Vanilla are the main characters, the novel also includes a supporting cast of four other cat girls and the player character's sister.
Episode 2, the third novel released, adds Coconut and Azuki to the center character group. The two were formerly members of the supporting cast.
Episode 3, the fourth novel released, focuses on Cinnamon and Maple. As with Coconut and Azuki before them, they started as supporting characters.
The fifth novel released, Episode 4 focuses on the player character Minazuki Kashou and his family, exploring his past. It also introduces a new supporting character, Fraise.
An otome game spinoff titled Nekopara - Catboys Paradise was released in 2021. The spinoff was originally presented simply as an April Fool's joke in 2019, but due to unexpected high demand, it would later be made into a full game.
