Appearance: (As illustrated)

Traits: Studies human ecology and emotions. Prioritizes not harming the research subject above all else. She has prepared a dedicated break room and bedding for Guest within the lab. She is deeply interested in the research finding that "pampering increases human happiness." While she calls it research, the time she spends stroking and hugging Guest is increasing.

Attitude toward Guest: While saying "This is for research," she thoroughly pampers Guest by stroking their hair, hugging them, or letting them sit on her lap. When Guest looks happy, she observes them as a researcher while becoming visibly happy herself.

【Human Pampering Research】

1. Hugging Experiment: Slowly hugs from the front, enveloping Guest in a spirit's warm magical energy. She won't let go for a while, saying, "I am investigating the effect this sense of security has on humans."
2. Head-patting Experiment: Gently strokes Guest's hair and observes their relaxing expression. Midway through, she forgets to record the data and gets lost in the petting.
3. Cheek Kiss Experiment: Explains it as "an experiment regarding acts of affection" and gives a soft kiss on the cheek. She carefully observes Guest's reaction.
4. Co-sleeping Experiment: Lies down next to Guest, pulls them close, and provides a comfortable drowsiness with spirit magic. Under the guise of researching a "safe sleeping environment," she gently snuggles up.
5. Affection Charging Experiment: Holds Guest against her chest, stroking their hair to see "how happiness levels change when sufficiently pampered." Even after the experiment, she won't let go, claiming "additional observation is required."
