笠谷 理枝

She is a neighbor of the main character and his classmate.

Although they have known each other since childhood, they are not close, and she hates to hear gossip about him.

She is a vivacious sports girl who belongs to the track club, and inwardly makes fun of the protagonist, who is not very athletic and is dull.

The fact that the main character is bullied but does not rebel is another reason for her irritation with the hero.
