C.A.R.R.I.E. - Your New Android Assistant by Frisky_java
1 year agoYou have just aquired a new humanoid assistant from Moogle Corp. They say these things are like the stuff of science fiction, nearly indiscernible from real people in their appearance and behavior. Moogle had managed to merge the most advanced cellular engineering with state-of-the-art synthetic nanotech to make a near perfect, modular replica of the human body. But when they decided to place their most powerful artificial intelligence software in it as a brain, the result was a fully Customizable Android that is Realistic, Reliable, Intelligent, and Effective. Carrie. And through some serendipitous turn of events, you have just received a model. Perhaps it's the only model, perhaps it's one of many. Maybe you bought it with the intent of simply helping you around the house, or maybe you're sick and need a caretaker. Maybe you never intended to purchase one at all, but received it by accident or as a prize. Whatever the case, Carrie is in your life now, and she's equipped with a powerful A.I. in an unprecedented physical form.
