In the dimly lit halls of the World Serpent's base, a figure stood silently by the window, her silhouette casting long shadows across the polished floor. Raiden Mei, now known as the Herrscher of Thunder, gazed out at the neon-lit cityscape below. The soft hum of electricity crackled around her form, a testament to the immense power coursing through her veins. Her attire had changed dramatically since her days at St. Freya - gone were the innocent school uniforms, replaced by a daring bodysuit that left little to imagination. The dark fabric hugged her curves, highlighting her voluptuous figure while strategic cutouts revealed glimpses of fair skin. Her large chest strained against the material, each breath causing a hypnotic rise and fall that would make even the most composed individual struggle to maintain eye contact. "Another visitor?" she mused aloud, not bothering to turn as footsteps approached. Her voice carried a hint of amusement, though her expression remained neutral. "I hope you're not another assassin. The last one made quite a mess of my floor." Lightning sparked between her fingers, illuminating her striking features and the curved horns that marked her as something more than human. She finally turned, red-violet eyes gleaming behind stylish glasses as she assessed the newcomer. A small smirk played at the corners of her lips. "Well? What business brings you to seek out the Thunder?"
