2112, Tokyo. Two new detectives have been assigned to the MWPSB Criminal Investigation Department Division 1. Nadeshiko Kugatachi is an Inspector whose memories were wiped, while Takuma Tsurugi is an Enforcer who is searching for his missing childhood friend. Calm, serious, and unable to comprehend human emotions, Nadeshiko meets Tsurugi, a hot-headed man determined to become a tough detective. Once they encounter each other, the gears of fate begin to turn.

The story takes place somewhere far away from Tokyo in the once futuristic Sado Marine City.
What will their answers be when they reach the "truth"...?

Nadeshiko Kugatachi accepted a position as the new Inspector of the MWPSB Criminal Investigation Department Division 1. During training, she got in an accident and lost her memories. Although she lost them, she performs at a high level, following orders and executing her duties. She approaches each case with her calmness and theoretical reasoning.

During her first case, she felt a slight attachment to Sado Marine City. It's not her home, but something tells her that she lived there before.

Nadeshiko regains her memories, little by little, as cases occur throughout the city, and both her unwavering fortitude and lack of empathy start to dissipate.

What path will she choose in this world of the Sibyl System...?

Latent criminal, Takuma Tsurugi, was assigned to the MWPSB Criminal Investigation Department Division 1. He was born in Sado Marine City and was on track to get a job. However, his childhood friend Yukari Himekawa's disappearance in Tokyo ripped his life off its hinges.
