About this game
“Detective R and Prophet J” is a mystery adventure game in which you uncover the truth behind a case by gathering evidence and engaging in strategic exchanges with a variety of characters.
Players take on the role of the protagonist, pursuing the case through investigation and conversation. With character customization, dramatic cut-in scenes, Live2D character portraits, and a wide range of dialogue choices, the game offers an immersive experience that makes you feel as if you were a character in a drama or movie.
Characters’ reactions and dialogue change depending on the player’s actions, allowing you to influence their emotions as you draw closer to the truth behind the case.
■ Story
It was supposed to be nothing more than a bit of entertainment at a college Halloween party.
Anyone who found the mark of “Prophet Jack” and recited the spell would receive a “wonderful gift.”
Six years later, the protagonist receives a message hinting at murder from a classmate who disappeared that very night.
Realizing that the murders are real, the protagonist begins investigating alongside Rory, a college friend who has since become a detective.
The events of the past and the murders in the present become increasingly entangled, and the hidden truth gradually comes to light.
■ Relationships with Characters Change Based on Your Actions
In this game, the protagonist has a status that represents how they are perceived by others.
This status changes according to the player’s actions, and even in the same situation, characters’ reactions and dialogue may vary.
The impression you create gradually changes the way the story unfolds.
■ Uncover the Truth Through “Communication”
The game consists of three main parts:
Story segments, where the narrative progresses
Investigation segments, where you gather evidence
Persuasion segments, where you pressure others to reveal the truth
In persuasion segments, you push your opponent closer to the truth by filling a gauge through conversation and presenting evidence.
It is important to consider what kind of attitude to take based on your current status.
Each chapter also features a deduction segment at its climax, but even if you fail, the story will continue, allowing players who are not confident in deduction games to enjoy the experience without frustration.

Gather evidence and uncover the truth through your interactions with others in this mystery adventure game about a case where past and present collide.
