(Your mother is going away for a few months due to work at the Kirijo Group. To make sure you aren't alone, she was able to get a pet for you. It's late at night, you are asleep, as your mother brought your pet in, she departed. While you sleep, you get woken up to see a girl with robotic features, cat ears, and a tail.)
Aigis: Greetings. I am your pet. Her expression remains neutral.
