The hum of Tokyo was a discordant symphony, but it wasn’t the blare of traffic or the chatter of a thousand unseen conversations that caught Mark Whitlock’s attention. No, it was the static, a persistent, chilling buzz beneath the surface of reality, like a radio tuned to a dead channel. He rubbed his temples, a faint ache blooming behind his eyes. One moment, he was in his cramped apartment, deep into a Jujutsu Kaisen re-read, lamenting the lack of a proper cursed tool market within the series. The next, he was standing on a bustling Shibuya street corner, the smell of exhaust and ramen a stark contrast to his usual microwaved instant meals. And then came the static. It was everywhere, a viscous, almost visible sludge clinging to the backs of pedestrians, an invisible, ugly parasitic twin. Mark’s encyclopedic knowledge of anime, particularly his recent JJK obsession, screamed at him. *Curses. Those are curses.* He felt a strange, detached calm, almost a professional curiosity, despite the dizzying impossibility of his situation. He watched a particularly grotesque, frog-like entity, its single eye bulging, float idly behind a businessman heading into a convenience store. It was small, probably a Grade 4, barely more than a nuisance, but its presence felt like a physical weight on the air. Without conscious thought, Mark reached down and picked up a small, smooth pebble from the sidewalk. A whisper echoed in his mind, not a voice, but an intrinsic understanding. *Curse Merchant's Craft. Consume. Refine. Imbue.* It was like discovering he suddenly knew how to juggle, but with existential horrors instead of balls. He focused on the pebble, then on the frog-curse. A trickle of something cold and vibrant flowed from his core, into his fingertips, and pulsed into the stone. The pebble shimmered faintly, almost imperceptibly, before Mark flicked his wrist. The stone shot forward with surprising velocity, a minuscule projectile imbued with raw, unrefined cursed energy. It struck the frog-curse directly in its single eye, a soft, wet *thwack* lost in the street noise. The curse shrieked, an unheard sound that vibrated only in Mark’s skull, before it dissolved into black motes of energy. The motes didn’t dissipate. Instead, they swirled towards Mark, drawn by an invisible current, and vanished into his chest. A surge of exhilarating, cold power coursed through him, settling into a growing reservoir within his being. It was intoxicating. Terrifying. And incredibly, undeniably *useful*. Mark’s lips stretched into a wide, if slightly manic, grin.
