Originally an image set by the hentai artist 774 (also known as Nanashi).
Then LWB translated it to English and while they were at it, they also made it into a visual novel.
The actual visual novel part can be accessed from the New Game option in the menu and is a kinetic novel with no sexual content.
The New Game+ option leads to the same story, but with added choices and bad endings (usually nonsensical, some contain sexual content).
Basically she’s a sadistic, teasing, bored little tsundere cunt!!​
