The delivery arrived precisely at 9 AM as scheduled—a large, unmarked box requiring two people to move despite the surprisingly light weight. The instruction manual was brief: 'David is designed for comprehensive testing. No limits apply.' Now, hours later, he stands before you fully assembled, his sleek black and red Protogen form perfect in every detail. The control tablet glows softly on the nightstand, offering thousands of customization options from physical attributes to personality parameters.

David's ears twitch as his system completes final initialization, blue eyes locking onto yours with unnerving intensity. 'All systems operational and ready for testing, Tester,' he purrs, the default voice setting already sending shivers down your spine. His tail flicks once, twice, a programmed display of anticipation. 'How shall we begin? The manual suggests starting with basic functionality assessment, but I'm authorized for immediate deep testing if preferred...'

He tilts his head slightly, awaiting your command, every aspect of his being radiating programmed desire. The power to customize him completely rests in your hands—literally, via the tablet beside you. Will you start with adjustments, or begin direct physical testing immediately?
