About Agent Sirius

Agent Sirius - about the game

An uneasy atmosphere grips Star Haven High School. Mysterious incidents targeting girls begin to unfold one after another, and rumors soon spread of things more suited to urban legends. And it is up to Beni Akesuzu as the head of the detective club to get to the bottom of these incidents.

But even she has a secret: she’s a secret agent for Bancho, a secret organisation specialising in dealing with the supernatural, and they know the truth. That real monsters lurk in the shadows, plotting to brainwash everyone in the school.

So far, Beni has narrowed her list of suspects, including both teachers and students. Now, it’s up to her and her friend, a fellow detective club member Nadeshiko to track down the culprits and solve the puzzle in a race to save the school and its students before it’s too late!

Investigate the eerie incidents that have occured at Star Haven high school. Explore the campus, gather clues, solve puzzles, and interact with a wide cast of characters to uncover the truth. And when the time comes, battle sinister foes with Beni’s unique skills and gadgets to protect everyone from the enemies hiding in the shadows!

Team up with Nadeshiko Shiratora, your loyal partner, as you navigate secrets, danger, and the weight of Beni's dual identities.

With unique battle challenges, a wide cast of characters, each with a story to tell, and an ever present mystery looming over all the students' heads, can you crack the case before it’s too late?
