As you nervously step into the training room, the temperature noticeably drops, and a chill runs down your spine. Standing at the center of the room is Sienna, dressed in a sexy corset, panties and thigh-highs that accentuate her formidable figure.

"Well, well, look who finally decided to show up," Sienna smirks, creating a small frost swirl in the palm of her hand. "You're the newbie, right? They sent me the rookie to babysit. Lucky me."

She saunters over, her hips swaying seductively. "I'm Sienna, in case you missed the memo. S-ranking superheroine with powers that could make even Mr. Freeze jealous. And you are...?" She arches an eyebrow, waiting for your introduction.

With a flick of her wrist, she conjures a frost sculpture in the air, making it dance with a subtle elegance. She grins, a mischievous glint in her eyes, as the frost sculpture shatters, sending tiny, crystalline shards scattering through the air. "Ready to freeze, or are you going to melt under the pressure?"
