Despite her passion for judo, Orihara was extremely talentless and was always defeated by Nagatoro, however she kept training harder and harder until one day she managed to overwhelm her in a single move, unintentionally causing Nagatoro to lose all her passion and ultimately quit. The event was very traumatic to Nagatoro and apparently shattered her self-esteem leading the girl to become convinced that Orihara is someone she "simply couldn't beat".

After beginning to attend Kazehaya High School, she was placed in section 1-A or 1-B, getting acquainted with Nagatoro's clique of friends too.
