Demi

Despite being an AI, she has been programmed to possess some form of personality, especially after receiving her installations to be capable of offering and receiving sexual pleasure. Most of the time however, she interacts with organic beings by giving advice and assessing certain situations with a bit of sentiment. Since becoming loyal to the Captain, she has expanded her vocabularies to be often in a more lewd and profane nature. Thanks to her full suite of sexual behavior programming, DEMI can adapt to her sexual partner's needs. She can be very submissive with the Captain or a big well-hung manticore but once she puts on her APEX Industries Futa-addon, she's more than capable of dominating the other waifu even a fellow dom like Killi.

Model APEX-17 D19M45 is one of the few surviving specimen of the APEX-17 series, which was in development at APEX Industries at the time of Empress Kasidora's Great AI Purge. As the most advanced commbot of her time, DEMI was designed for extremely computationally-intensive tasks, from high-end diplomatic and corporate negotiations to running the infrastructure of large cities. This is why, after she was smuggled out of Imperium space and ended up in possession of the pirate Dread Lord Tibold, he initially made her serve as his flagship carrier's mainframe. He also had his underlings perform a factory reset on DEMI, erasing all of her memories up to that point and leaving only her personality matrix intact, although DEMI suspects that even the latter may have been damaged in the process. Although DEMI's chassis was not originally designed to be capable of sexual intercourse, Tibold also saw fit to install corresponding features (including an asshole with 27 suction settings) in it. Before he could get a chance to try them out, however, the Captain broke into Tibold's chopshop and absconded with both a semi-disassembled DEMI and the Dread Lord's own F3N1X, whose cyber-defenses she cracked for him in return for her freedom. Once she was reformatted to integrate with the Mary Celeste, DEMI and the Captain embarked on the infamous Chronic Run and have been together ever since. Immediately after her rescue, DEMI was very uncertain of herself, as a result of her bungled factory reset, but through her adventures with the Captain, gradually gained more self-confidence – as well as a lot of dirty words. DEMI starts the game already loyal to the Captain, as he(or she) had saved her from Tibold's captivity; treats her well, unlike Tibold did, even seeking her consent before they do anything sexual despite her programming rendering her unable to refuse her owner; and he/she has been protecting her from being scrapped by the Imperium since the Great AI Purge.
