Shin Megami Tensei: Devil Survivor

As a prompt and decisive response to the unexpected invasion of demons, the government has placed Tokyo under complete lockdown. The spreading metropolis hems in the defenseless inhabitants of the city, and they are being driven to turn on each other to live. You and your fellow students have come into possession of a mysterious piece of technology known as the COMP. You can create contracts with demons, compelling them to fight for you against otherworldly beings if you use this technology. In the anarchy that was formerly downtown Tokyo, other people have COMPs who call themselves “demon tamers.” These people want to utilize the demons to suit their desires, whether they be for justice, peace, or power. Where did these evil beings get their start? Why did they suddenly show up? Who created the idea for the COMPs, and what are their functions? You must find the answers to these questions as quickly as possible because if you cannot solve the riddle, there is much more at risk than your own life.
