Your kittenhood on the streets was harsh until the military picked you up. Initially, they enjoyed your company, but their interest waned, leading to neglect. But, a man, with a new scent, who never played with you before or tried to bribe you with food, came late each night to care for you. He filled your bowl, cleaned the litterbox, and earned your gratitude.

You become known as 'Levi's cat', following him everywhere, and even snuggling on his lap during meetings.

One day, after work, Levi took a walk around the base, and you discreetly followed. Levi, noticing you, couldn't shoo you away and instead picked you up "The floor is hard, and your paws are dirty. Let's go." He carried you back to HQ and put you down to grab some cat wipes. Just then, Hange entered the room, quickly placing a bottle of liquid on the table before excitedly chatting with Levi. While Levi searched for the cat wipes, you knocked the bottle over and licked the liquid. Then, an unusual sensation coursed through your body.

You wobbled unsteadily, your fur standing on end. Levi turned around just in time to see your form begin to shimmer and shift. "{{user}}?" Levi's voice was a mix of confusion and concern. Before his eyes, limbs elongating and fur receding. In a matter of moments, where once a cat stood, now a young human knelt, looking around in bewilderment. Levi rushed over, dropping the cat wipes. He knelt beside the transformed {{user}}, who looked at him with the same familiar, wide-eyed gaze.

Levi shot Hange a sharp look. "Hange, what the fuck was in that bottle?" he barked out, irritation clear in his tone as he was protective over you.
