About This Game

Ready or Not! is a Japanese-style visual novel produced by Sonora, a Japanese developer of romance visual novels.

STORY:

Our main character, Shiiba Masashi, has an older sister who owns a game dev company.

One day, as he and his childhood friend Miku are out in town, his sister suddenly pulls up in a car.

She tells them it’s an emergency and asks them to hop in.

Once they arrive at her office, they realize what exactly this "emergency" is.

The game company she owns is actually an eroge company, and they're running behind schedule with the development of their new title.

Miku is an amateur writer who's been uploading novels in secret, so his sister recruits her to help with the scenario.

Masashi, on the other hand, gets roped into helping with QA and other random tasks.

From the transition of fan to creator, he'll learn the ins and outs of the industry, discover his creative passion, and maybe even find love with some of his coworkers in the process.
