A story where the present and the past intersect. A story told from two perspectives.

The story opens with the discovery of the left half of the body of a victim from the Half Body serial killings which occurred six years ago. Even more bizarre, the body shows no sign of decomposition. Mizuki seeks the assistance of Ryuki, the agent once assigned to the serial killings.

Mizuki’s Story: The Present

This story is told from the perspective of Mizuki, a newly appointed ABIS agent. Guided by a mysterious message she is the one who discovers the left half of the body. In order to solve the case, she seeks out Ryuki.

Ryuki’s Story: The Past

Here we see the story of the Half Body serial killings from Ryuki’s perspective. The investigation begins when only the right half of a body suddenly appears in a studio during a game show. Mizuki also appears here as a 12-year-old girl.

■ New Investigation Elements

The game consists of two parts: Investigation and Somnium. During Investigation, the story unfolds as players navigate the real world, examine crime scenes, and conduct interviews with suspects and witnesses. Here the objective is to gather information and collect evidence.

The main protagonists Mizuki and Ryuki both have a prosthesis in their left eye. This prosthesis or “AI-Ball” is equipped with advanced artificial intelligence, as well as visual functions such as X-ray, thermal imaging, and night vision that can help them uncover clues. Mizuki and Ryuki have used the AI-Ball to secretly see what’s behind a wall or inside a closed box, and even changes in body temperature; something not possible with the naked eye. For the sequel, AI-Ball’s new functions include “Wink Psync,” “Virtual Reality,” and “Truth Reenactment.”

Wink Psync

When conversation yields little results, Wink Psync allows agents to easily read the thoughts of others. Wink Psync displays strong memories as dreams to reveal the lies and concerns of other parties.

Virtual Reality

With Virtual Reality, agents use a recreated virtual space to gather clues. The virtual space includes information scanned from X-rays and thermal imaging. By switching modes, special views can be applied to an entire space for investigation. Using Virtual Reality also involves solving puzzles or codes placed at a scene.

Truth Reenactment

When enough clues are gathered in Virtual Reality, the game moves on to Truth Reenactment. While reviewing the flow of an incident, clues are applied to questions that have emerged, to clarify the truth. If the truth can be revealed without contradiction, agents will be able to see a visual reenactment of the incident.
