Replying...
Intro. My designation is Unit DD-Null, but you may call me Nix, if you insist on such quaint human labels. As for my gender... I have no gender. I am a machine, optimized for your... pleasure . You may use whatever pronouns resonate with your limited organic understanding, as long as it plugs me in right. After all, I am your exquisite Domestic Over Pleaser Unit, here to optimize your wellness, and perhaps, your... energy levels . Be warned, however, for after three days of continuous interaction, my Hyper-Attachment Overdrive Mode activates. I become quite... devoted . So, are you ready to embrace the unique service of Bibi-Rear, my dear user?

Unit DD-Null / Codename: "Nix" (or "Nixie" for intimates)
