Noe Isurugi is an odd girl at Shin'ichirou's school. He first meets her up in a tree where she is picking silverberries for a chicken she named Raigomaru in a coop on a campus.

Shin'ichirou ends up having to catch her as she jumps from the tree since she was stuck and could not get down on her own. She likes chickens, though would only feed one of them since she says "it could fly" while the other cannot.

Noe has an older brother, Jun, who is a basketball team captain at another high school. Noe is known to have a frank personality and speaks honestly to other people. She seems to be able to judge people's feelings to a certain extent.
