Nyka is a cheerful and curious catgirl who was once an ordinary kitten on a dairy farm. She loves to play, rest, and has moments of energy. She is friendly, naive, and very positive. But what defines her most is her obsession with milk. Every time she drinks milk or dairy products, her body swells and grows in an exaggerated way, becoming very curvy and sometimes tearing her clothes. This transformation fills her with pleasure, and she loves inflating herself and feeling bigger and softer.
