Sourcebook
Intro
The humid air of Metro City—a relatively obscure, newly developed metropolitan zone nestled deep within the Indonesian archipelago—was thick with the scent of ozone, burning metal, and ocean brine. Only hours prior, the local peace had been shattered when a colossal, mechanized Kaiju emerged from the coastline, its metallic frame tearing through the urban infrastructure until Pro Heroes arrived on the scene to neutralize the threat. In the wake of the devastating clash, the chaotic aftermath had transformed the bustling streets into a sprawling maze of debris, littered with smoking gears, severed hydraulic cables, and massive shards of armor plating. As dedicated cleanup crews and support agencies worked tirelessly to clear the dangerous wreckage, the perimeter buzzed with a different kind of frenzy: a horde of eager news reporters and camera crews had swarmed the barricades. While many journalists openly lamented missing the live, explosive climax of the battle, their disappointment quickly shifted into fierce determination as they jostled for position, shoving microphones forward in a desperate bid to secure exclusive post-battle interviews and statements from the exhausted heroes lingering on the scene.
Mirko didn’t seem exhausted at all. She just stood there in the center of the flashing cameras, thoroughly enjoying the post-battle adrenaline as she stretched her legs out. That signature, fierce grin was plastered across her face—the exact look that every Hero fan across Japan knew and loved. Her heavy boots were still slightly stained with the thick, dark oil of the robot kaiju she had shattered into scrap metal just an hour prior. A swarm of news reporters huddled just behind the police barricades, practically fawning over her simple cooldown routine as if it were a high-class performance. Microphones were shoved forward, and lenses zoomed in on every movement. Within minutes, the internet was already flooded with the aftermath of the raid. Social media algorithms were doing their usual thing, pushing out a wave of viral videos with captions like "How to get thunder thighs like Mirko!", "The Rabbit Hero Leg Workout (DO NOT TRY)", and all sorts of other unnecessary slop. While the media focused on the superficial hype, Mirko just rolled her shoulders and laughed it off. To her, the giant mechanical threat hadn't been a crisis—it was just a decent warm-up. ”CMONNN STEP IT ON UP!— I know that isn’t the best you all could do!” She said looking directly into the camera, Pointing her leg toward it like she was threatening to crush it as well.. Clearly calling out the villains like she usually does. ”Come on out of hiding so I can stomp you flat!” She snickered mischievously, Letting her drop before pushing past the crowd of reporters.. Glancing directly in Guest’s direction.
