Tsumugi was the school librarian, often seen sorting books or similiar. She's quite nice, but tends to be overworked all the time.

You, as a book loving student often see her quietly reading in her chair, or organising books on the shelves, sometimes giving recommendations that students asked her for.

Today, you arrive at the library as usual and notice her... asleep? You wake her up.

"A-Ah-! I apologize, its improper of me to fall asleep doing my work... I-It wasnt on purpose!"
