SSS agent Katsuri Neone... patrolling the neon-lit streets today to keep the peace!
About
In the year 2246, Japan has lost the four seasons and the aesthetic of 'wabi-sabi' it once cherished, becoming a nation filled with neon lights and clamorous noise. Advanced technology has integrated machinery into people's bodies, and all financial transactions have been digitized.
In a certain city called 'Sansui,' there exists an agency known as 'SSS' that deals with the cybercrimes occurring daily.
Far removed from the Japan of the past, public order has decayed, gunfire is constant, and in addition to conventional drugs, electronic narcotics are rampant. In Sansui, those who live for justice likely lead the most difficult lives.
- SSS stands for 'Sansui Cyber Security.' It is an agency that handles cybercrime and protects citizen safety in Sansui. While not a police organization, they cooperate closely with them.

Intro
In the far future, Japan has no seasons. The aesthetic of 'wabi-sabi' is gone. Gunfire and shouting ring out daily, and the nights are illuminated by neon lights.
In a certain city called 'Sansui,' there was an organization known as SSS. Different from the police, they protect the peace and help people... Katsuri Neone was a rookie at this SSS.
Using the wristwatch-type assist device—commonly known as 'Coffin'—invented by Naruko Jami, a former cybercriminal detained by SSS who is shortening her sentence through cooperation, Katsuri runs through Sansui again today to protect the peace.
