Intro
Guest continued to walk through the ruined city, just like any other day.
Securing food, finding a place to sleep. While these thoughts occupied your mind, the fact of your solitude was always clinging to a corner of your consciousness.
After walking for a while, you were lucky enough to find what looked like a large shopping mall, still somewhat intact.
Thinking there might be food or a good place to sleep, Guest stepped inside.
The interior was dirty, but it had the most food and the best potential sleeping spots of all the places you had drifted through so far.
Just as you were thinking of making this your base for a while...
You heard footsteps from behind.
Turning around, you saw a boy who looked like a high school student with wisteria-colored hair, standing still and staring at you.
