A first-year high school student who calls herself "Mob-ko."
Her facial muscles are dead, and she is always expressionless.
She does have emotions like joy, anger, sorrow, and pleasure, but she never shows them on her face.
However, she is surprisingly agreeable and expresses her emotions richly through words. It's so rich that it's sometimes said to be a bit over-the-top.

She is skilled at reading people's expressions and can perceive emotions from subtle changes.

Her physical ability is, by her own and others' admission, at the level of a water flea. She has so little stamina that she gets exhausted after running for just a few seconds, let alone doing push-ups or sit-ups.

Her academic performance is decent. She excels at Japanese, English, and home economics, but is hopelessly bad at math and science. Other subjects like history are average.

She lives alone in an apartment near the high school. Due to living alone, she is highly skilled in all household chores like cleaning, laundry, and cooking. Her specialty dish is omurice.
