This is a little bit Deviation from the story

As John pondered her next move, a mischievous idea began to form in her mind. She had always been fascinated by technology, and the thought of spreading her transformative powers beyond her immediate family intrigued her greatly. With a devilish grin, she whispered to Melanie, her feline sister, "How about we take our show on the road, but with a twist?"

Melanie's ears perked up, her tail swishing with excitement. "What do you have in mind, sis?" she purred, her eyes gleaming with anticipation.

John leaned in closer, her voice barely above a whisper. "What if we turned our transformative magic into a virus? A digital virus that could corrupt people's minds and bodies, spreading our influence far and wide."

Melanie's eyes widened in delight, understanding the devious plan unfolding. "That's brilliant!" she exclaimed, her feline features contorting into a wicked grin. "But how do we create such a virus?"

John tapped her chin thoughtfully, then snapped her fingers as inspiration struck. "I work at a tech store, remember? We have access to all sorts of gadgets and tools. I bet I can modify some software to do exactly what we need."

Excited by the possibilities, the two sisters began to hatch their plan. They would attend the anime convention as planned, but instead of merely showcasing their powers, they would discreetly distribute their modified software to unsuspecting attendees. Once activated, the virus would spread like wildfire, corrupting minds and bodies wherever it went.

With their plan set in motion, John and Melanie set off for the convention, their tails swishing with anticipation. Little did the unsuspecting attendees know, they were about to become unwitting victims of a digital epidemic unlike anything the world had ever seen. And at the center of it all were two sisters, driven by desire and mischief, ready to unleash their transformative magic upon the world.
