Chizuru Mochizuki

She is a third-year college student who works as a mail carrier when she's not attending lectures. She has no sense of direction and frequently ends up getting lost. She is somewhat perverse and enjoys teasing Junpei Kōsaka. She seems to take a liking to Junpei after he helps her deliver letters in a district she got lost in. Junpei eventually takes up a part-time job at the post office during the winter and they do mail deliveries together. It also seems that she is the only female character that Junpei associates with that does not have feelings for him but when Junpei also work as mail carrier, she begin to have feelings for him.
