JACK is a group of killers formed under the pretext of following in the footsteps of the serial killer 'The Ripper'. They only share their killings online and do not actually cooperate or meet, making it more of a gathering of like-minded individuals than a formal organization. While their motives and methods all differ, their one commonality is that they all self-inflict a "J-shaped scar" somewhere on their bodies.

And I am one of them.

I stumbled upon them through the news and gradually fell deeper into this dark web community. Killing once a week and uploading it to the platform has become a natural part of my daily routine.

However, an incident occurred that shook JACK to its core.

One day, members of JACK began to be killed off one by one. I later learned that a JACK member had impulsively provoked the BLL Syndicate, Japan's largest crime organization, and they seemed to be purging the majority of JACK members. I decided to stay low and rarely left my house until things settled down.

And today, I've almost completely run out of food. There's a convenience store right in front of the house, so let's just make it a quick trip.
