However, in winter she is shown to wear a light brown sweater. She has also prominently been shown wearing her.

Personality
Orihara is very carefree, energetic, easy-going and kind, seeing Senpai lost in the first year floor, she didn't hesitate in offering to help him find the person she was looking for, was very welcoming to him, tried patiently to understand who "Nagatoro" was - since she usually called her "Hayacchi" - and, after explaining him where to find her, stood with the arms on her sides sporting a satisfied expression, happy to have been helpful. She's also described as a very honest girl and has an extremely sporty attitude, always wishing the best to the opponents, being kindly full of advices to fellow judokas, worrying deeply if someone got injuried, nicely hoping to have "exciting matches" with the rivals and looking far to have matches with them. A positive and hard working person, Orihara has trained very hard to get better at judo, starting very incompetent and turning into an Olympic candidate.

Orihara is completely devoid of any kind of malice, exhilarated and easily excitable, to a point that Nagatoro describes her as "a pain" but, nevertheless of this, seemingly have some respect for her and, in stark contrast with it, Gamo-chan greatly enjoy her company. Also, even when scolding someone, she acted nicely and smile kindly. On the other hand, Orihara seems to consider Nagatoro a friend, a feeling that's clearly not reciprocated. Also, Orihara doesn't seem to be that bright, as she's always depicted completely unaware of how much Nagatoro is irritated by her.

She started practicing judo as a kid and met Nagatoro in the very first dojo they both went to; despite the latter never really get along with her Orihara started to consider her a friend and always referred her by the pet name "Hayacchi". 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.

Embarrassed Senpai admitted to himself that he didn't know, then however he remembered that her friends called her "Hayacchi", causing the girl to realize who she is and subsequently telling him to look for her in section C.

Judo Tournament
At the school's judo tournament, Orihara easily defeated Gamo-chan, winning the match and thus having to face Nagatoro in the following one. Overjoyed for the opportunity to fight with Nagatoro once again, she happily told her she expected to have an exciting match with her, inadvertently leading the girl to get a little discouraged, despite Orihara's intentions being absolutely genuine and friendly. When her match with Nagatoro began, the two girls appeared to be equal in terms of skills, however due to being given as favorite, everyone in the hall except for Gamo-chan, Yoshi and Sakura started to cheer for Orihara, which leaded Senpai to cheer for Nagatoro as she previously did for him. Despite blushing for it, Nagatoro was quite pleased and gained enough confidence to slam Orihara on the floor getting a waza-ari, but eventually she lose by points. The match however does restored Nagatoro's passion for judo, leading her to shaking Orihara's hand after losing and promising her that she would have definitely "get her" next time.

Nagatoro was visibly embarrassed by the chat between her best friend and her rival; however, despite firmly denying the boy in question being her boyfriend, when Orihara suggested her to choose between love and judo, she indirectly state she would have both.
