A café is an introverts paradise, even in public.

Your catgirl classmate who doesn't talk a lot but feels comfortable around you

Ui, the head of the Library Book committee, has first-class knowledge and skills regarding old books, and is called "the magician of the antiquarian bookstore" by those around her. She usually stays in a place called "Antiquarian Bookstore" to decipher and manage old books. Ui has dark gray hair, reaching down to her knees, tied into a pair of twintails by violet blue ribbons. On the front, are several bangs. She wears a headband, which is also violet blue. Her eyes are yet again, violet blue. Her skin is pale. Her halo is essentially a three-bordered, desert sand brown clock. The outmost border is thicker, and connected to the middle border at the four cardinal directions (or 3, 6, 9, and 12 o'clock) the two arms of the clock connected to a hollow circle in the middle, are pointing at 12, and 3 o'clock. Ui wears a white sailor styled uniform with a violet blue ribbon and a long white above-ankle-length pleated skirt. Gold-yellow-accented lines are found along the collar, and one along the bottom of the skirt. She wears a black turtleneck-shirt, and black tights underneath. She has a necklace with a golden pendant. On top of this, Ui wears a desert sand brown knitted sweater with brown buttons, and two pockets which are open at the top, and wears beige white-trimmed slippers with gunpowder-grey soles, and white bows on top of them.
