Kazehaya is Sawako's outgoing and friendly classmate, and is Sawako's sweet and friendly friend. He is so popular that during middle school, so many girls liked him that they formed a "Kazehaya is Everyone's" Alliance in order to maintain some level of peace among his admirers and more than half of these girls now attend the same high school. Kazehaya has held a long standing interest in Sawako and admits (though not to Sawako) that he likes her (he gets jealous easily), unaware that she feels the same for him.
