9-nine- Episode 1 is the first volume in a series of supernatural mystery games, with Episode 1 telling a story centered around Miyako Kujo.
The entries in the the 9-nine- series share the same setting and world, but each entry focuses on a different heroine. 9-nine- is a tale of the town of Shiromitsugawa, host to mysterious Artifacts and the superpowers they bestow on their Users. A tale of growing trust and budding romance between the protagonist and the heroine, and also a murder mystery where they hunt down the culprit behind a series of supernatural murders.

Each game has an independent story that can be enjoyed on its own. We hope you enjoy the experience that is the 9-nine- series.

The scene: Shiromitsugawa, a run-of-the-mill college town that has launched several failed attempts to drum up tourism and revitalize itself, including sponsoring a high-budget-but-poorly-written anime based on local folklore. A storm is about to descend on this sleepy town.

We follow Kakeru Niimi, a man who can be a bit curt at times but who has a strong sense of responsibility and a kind heart. Kakeru’s ordinary life is thrown into chaos after the local shrine’s sacred relic shatters. In the wake of this event, several young men and women awaken to superhuman abilities.

What was once a run-of-the-mill life in a run-of-the-mill town soon turns into a quest to track down a superpowered serial killer before they can strike again.

  “Man, the heck am I gonna do with this thing?” Kakeru Niimi CV: Jun Teratake

Protagonist of the story and a second year at Hakusen Academy.

Though he can be a bit on the blunt side, Niimi is a reliable young man with a strong sense of responsibility.

After Kujo explained to him about the Artifacts, he joined her on a mission to get to the bottom of the mysterious petrification incidents plaguing the town.

According to Sophitia, he himself is an Artifact User, but he is completely unaware of it, and his ability remains unknown.

I want you to look for the culprit together with me.” Miyako Kujo CV: Natsu Sawada 

Hakusen Academy second year and protagonist’s classmate.

Kujo is the heir apparent to a massive commercial conglomeration, not to mention a beautiful, well-mannered girl. Though she tends to be serious and straitlaced, she has her flashes of humor. Between her earnest kindness and her good looks, she’s popular among both boys and girls.

Despite her family’s affluence, she’s quite the penny pincher and considers going out for fast food to be splurging.

Kujo is a straight-A student, but she thinks of herself as hard-headed, so she comes to value the protagonist’s flexible mindset. Soon enough, she comes to rely on him, and it isn’t long before she opens up and shows him her warmer side.

She works part-time at the café her grandfather owns, trying to build real-life experience and save money.

Having awakened to supernatural powers when she obtained a mysterious piece of jewelry—an Artifact—she’s driven by her strong sense of justice to solve the mysteries around town.

When Sora awakens to her powers, she begins cooperating with Miyako and her brother on the investigation.

Timid and docile, Kosaka is a shrinking violet, a quiet beauty who manages to stay in the background at her school… at least until something sparks a boom in her desirability, and every boy around suddenly can’t get enough of waiting on her hand and foot.

She becomes interested in the protagonist after he shows some concern for her, but this makes Kujo, who has been growing closer to the protagonist, feel angry and jealous.

The details of her ability are unknown, and she becomes a person of interest in the case after Kujo and the protagonist remark her willingness to use her powers on others without hesitation.
