Sigil Online: I became the duke's third son - Chapter 5 - 0

Waking up in an unfamiliar world with no memories, I had only one advantage—a mind filled with knowledge of fictional tropes, clichés, and common sense learned from countless novels.At first, I thought I was trapped in a romcom nightmare when I started triggering events like “Helping a Girl on a Rainy Day”, “Damsel in Distress”, and “Tripping Into the Heroine’s Arms.” Naturally, I shut those nonsense down before they could escalate. No forced romances. No misunderstandings. No cringe.But something was clearly off.The world wasn’t just a slice-of-life comedy.Beneath the cliché academy setting, there were whispers of awakening powers, hidden dangers, and a brutal magic academy entrance exam.And every challenge I prevented or manipulated was an opportunity to grow stronger.[Title Earned: Background Character.][Achievement Unlocked: Firm Mind.][New Skill Acquired: Background Character's Aura.][New Ability Acquired: Anti-Narrative Influence.]I may be just a background character, but if fate insists on throwing these events at me, I’ll turn them into stepping stones.Let the protagonists play their scripted roles—I have my own path to power.

Japan – National News BroadcastThe polished news anchor sat upright, her gaze sharp as she adjusted the stack of papers before her. The newsroom behind her hummed with quiet urgency, the weight of the moment settling over the broadcast.“Authorities are baffled by a sudden and unexplained surge in sleep-related deaths across Japan,” she began, her voice steady yet tense. “More and more citizens are passing away in their sleep without any prior health concerns. Experts are working tirelessly to determine the cause, but no clear explanation has emerged. Authorities urge the public to remain vigilant and report any unusual symptoms before bedtime.”A graphic appeared, displaying the spike in fatalities over the past month. Behind her, unsettling photographs flickered across the screen—blurred images of individuals found in their beds, their faces frozen in expressions of terror.The anchor’s tone shifted. “Health officials recommend citizens avoid excessive fatigue and maintain healthy sleep habits. More updates will follow as investigations continue.”---United States – Paranormal PodcastIn a dimly lit podcast studio, the host leaned forward, his eyes wide with curiosity. Across from him, a rugged man in a worn flannel shirt, gripping a faded photograph in one hand and a beer can in the other, leaned back in his chair.“So, you're telling me you saw this creature firsthand?” the host asked, clearly intrigued.The man scoffed, shaking his head. “Damn right, I did. Ugly thing had wings bigger than my body—slow but sneaky. Thought it could steal my pigs again, but I was ready this time—camera in one hand, shotgun in the other.”He slammed the table for emphasis, then shoved the blurry image toward the host. The photograph depicted a small, red-skinned humanoid figure with large, bat-like wings, its eyes glowing faintly in the darkness.“Spit, the thing didn’t know what hit it when I fired!” the man chuckled, his voice full of excitement.The host held up the picture to the live chat. “Alright, what do you think? Mothman? Demon? Or is our friend here just seeing things?”The chat exploded with theories—some skeptical, others eager for the investigation to continue.---China – Liangyuan Street MarketSurveillance footage from a bustling night market in China captured a chilling scene. A woman in a red qipao walked gracefully through the crowd, her figure striking in the soft glow of lanterns.Suddenly, she paused. Her body flickered—like a glitch in a video—before vanishing completely, as though she had never existed.The footage zoomed in, replaying in slow motion. In the final frame before she disappeared, her face distorted unnaturally, her eyes hollow and empty.The screen cut abruptly to black.
