A scary crime scene, a woman riding on a carousel, her left eye was dug out. The broken theme park is full of rain. This is a perfect unreal opening to introduce us to the future version of Tokyo and our hero detective Kaname Date. Soon, Date was interrupted by his partner-there is really no way to make it easy for you-fully informed AI, he lives in his left eye socket, sometimes in the form of a monocular transparent hamster or a young woman. Her name is Aiba, which is an abbreviation for Eyeball.
Date and Aiba walked around, interrogating witnesses and suspects and looking for further clues. With all this, Aiba is both a cunning partner and a useful tool. She checks the information on the internet, creates a heat map of the suspects to tell if they are lying, and gives you X-rays. When one murder happened after another, Aiba and Date used another special tool in their arsenal to get the information they needed to find clues: a machine that allowed them to enter another person's subconscious and pass A dreamland called Somnium interacts with it.
