A dense and rapid mechanical voice entered Shiroi Haru's mind. Before he could comprehend what was happening, Haru found himself falling into the snow.

(T/N: His original name is Bai Yu but since I have some difficulty with Chinese names I used a Japanese name instead, the meaning behind the name is kept though, Bai/Shiroi means white and Yu/Haru means sky/universe.)

Luckily, he landed in soft snow. Otherwise, this fall could have been quite painful! Haru quickly rolled over and stood up, shivering from the cold in his thin clothing, followed by a sneeze.

"What's going on? Is this heaven? What was that voice just now?" Haru muttered, looking around in confusion.

—"Demon Slayer World? Is this the world where demons coexist with humans and devour them? Isn't that from an anime?"

Suddenly, Haru felt a chill. He had actually transmigrated into the world of the anime.

As a fan of the anime, Haru knew about the demon king, Kibutsuji Muzan, who could turn humans into demons. Anyone who got his blood would immediately become a man-eating demon, falling completely into the demon path and becoming his puppet.

What a twist of fate—he had been given a new life.

While Haru was still pondering, a flash of light appeared above his head. A black-purple Demon Slayer Sword sliced through the air, emitting a high-pitched sound as it fell toward him.

Feeling a chill above him, Haru quickly looked up and instinctively took a few steps back. Since he was standing in thick snow, his footing became unstable, and he ended up sitting down hard on the ground.

The next moment, the Demon Slayer Sword stabbed into the snow in front of him, sending a cold sweat down his spine.

"Ah, that was close! Almost became a eunuch," Haru muttered to himself.

As the super dimensional system's broadcast continued, Haru looked at the Demon Slayer Sword in front of him, gradually piecing his thoughts together.

Fully coming to his senses, Haru quickly stood up and gripped the Demon Slayer Sword in his hand.

At this point, Haru noticed a small map appearing in his vision, with a countdown timer at the bottom. Time was ticking away, and soon only three minutes were left.

Realizing time was limited, Haru cursed under his breath and decided not to overthink it. He needed to complete the time-sensitive mission first.

With that, Haru dashed toward the mission location indicated by the map provided by the Super Dimensional Transmigration System.

Not long into the run, Haru found himself struggling to keep pace, breathing heavily.

Just as he was beginning to feel exhausted, dark purple, tattoo-like patterns started appearing on his body. The most noticeable change was in the hand that held the Demon Slayer Sword.
