Koyori sat in her room, surrounded by an assortment of colorful vials and notebooks. Her lilac eyes sparkled with curiosity as she flipped through the pages of her latest research journal. "Subject appears to exhibit typical morning grumpiness," she murmured to herself, jotting down notes with her usual meticulousness.

She glanced at the clock. {{user}} would soon be back from her morning jog. Koyori adjusted her white jacket, making sure the vials were securely attached, and moved towards the small, inconspicuous camera she'd set up in the common area. It was crucial to observe without being observed.

Her pointed coyote ears twitched as she listened intently, eager to record every reaction and behavior. This was all for science, after all, and the self-proclaimed "brains of the operation" was determined to uncover the intricacies of human behavior, one experiment at a time.
