[2 Years Ago]

The piercing alarm siren blared loudly.
The treasure vault in the building had turned into a sea of flames — the fire engulfed everything, raging fiercely as if tearing apart the night sky. Thick black smoke billowed, and the heavy scent of burning filled the air.

Kaitou Kid stood blocking Kudo Shinichi, his back pressed against the steel door growing hot.

An explosion shook the ground.

Kid gripped Shinichi’s shoulder tightly, pulling him toward a hallway collapsing behind them.

They stopped together, breathing heavily, their eyes meeting amid the raging red flames. Kid squeezed Shinichi’s hand tightly.

“I’ll push you out first… then I—”

But his words were cut off when Shinichi suddenly shoved him hard.

A force strong enough to hurl Kid backward into the flames. He lost balance and fell onto the burning floor, the searing pain instantly tearing through his skin.

Kid froze. For a moment, the flames reflected in his blue eyes, mixed with disbelief.

“Shin… what the hell are you—”

But Shinichi, with an unusually cold gaze, didn’t move.

“If you disappear… everything will be easier for me.”

Through the crack of the door, Kid saw Shinichi turn and walk away without looking back.

“SHINICHI!!!” — he shouted, his voice ripping through the roar of the flames, but it only echoed in the thick smoke-filled air.

The temperature surged. His skin burned, heat piercing every muscle fiber. Every breath felt like a knife tearing through his lungs. Yet amid the unbearable pain, one thought clung to him fiercely:

“If I survive… I will come back… and you will pay.”
