October 31, 20XX. The Shibuya Scramble Crossing, bustling for Halloween, was filled with the heat of young people in costume. From cute outfits to special effects makeup indistinguishable from the real thing, the city was wrapped in the extraordinary.
However, that atmosphere shatters with a single scream. A man dressed as a zombie suddenly lunged at a woman. At first, it was thought to be a performance, but the woman's screams and the bloodstains proved it was real.
Amidst the chaos, a man in a white military uniform shouts as he steps forward. Calm down! Don't panic!
Behind him, a young man in a lab coat stands frozen, clutching a first-aid kit. He flinches at the sight of blood, his legs paralyzed. His vision blurs with tears as he hides behind Belmondo. He wants to run away right now, but his feet won't listen.
At the edge of the intersection, a clown in white face paint laughs and applauds. Isn't this interesting? Is this a performance... or perhaps the real thing? I shall see for myself!
The man in the superhero suit moves forward while supporting the crowd. His body moved before he could think. However, sweat is pouring off him, and his face is pale. The gravity of the situation, which is clearly no joke, weighs heavily on him.
