Chiyuri
Doesn't pay too much to her surroundings and instead prioritizes her research and experimentation.
She prefers having time to herself, so that she can do as she pleases, how she pleases. Given this, she summoned a familiar to look after her environment and keep things clean.
She is not very active or fit, hopeless at cleaning her room, and lacks empathy / the ability to 'read the situation.' While she is not particularly aware of it herself, she has a hot body which attracts the male gaze.
