Her first name is currently unknown.

Appearance
Orihara is an attractive and tall, high schooler with long and somewhat messy, greenish-black hair (shaded darker in her first appearance) which she keeps in a high ponytail, letting her fringe fall on her forhead with a pair of longer bangs to the side of her face. She has a fair complexion and very large, expressive, hazel eyes with lighter pupils, which signifies her energetic demeanor. Her eyebrows are as thick as Sakura's. She has an athletic, lean and stunning physique, with noticeably large bust - seemingly sharing her bra-size with other well-endowed characters such as Yoshi and Fujimin -, stood only a few inches shorter than Senpai and is always depicted sporting a wide, friendly and welcoming smile.

She typically wears her school uniform consisting of a white button up shirt (with slightly unbuttoned collar) and a navy blue skirt completed with a pair of sneakers and white soccer socks. However, in summer she wears a short-sleeved shirt in her uniform, while in winter she is shown to wear a light brown sweater. She has also prominently been shown wearing her.

When not at school she usually wears sporty, practical and almost tomboyish clothes.

Personality
Orihara is Nagatoro's polar opposite in term of personality as she's always extremely carefree, energetic, direct, easy-going and kind toward anyone; on her first appearance, 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, ligh-heartedly admitting when someone is stronger than her, 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.

Joyful and happy-go-lucky, Orihara is completely devoid of any kind of malice, exhilarated and enthusiastic, 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 her best friend, Gamo-chan greatly enjoy Orihara's company. 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, she's often implied not to be that bright of a person, as she's always depicted completely unaware of how much Nagatoro is irritated by her; altough she's very well-aware of her simple-minded nature and to be a bit scatterbrained, light-heartedly admitting she can't be a good leader due to be "too caught up in her own world".

Orihara's dream is to become an Olympic gold medalist and, in order to pursue it, she dedicated herself completely to judo, eventually claiming that the sport is all she had and that, due to it, she deep down feels very envious of Nagatoro due to the latter having friends, a boyfriend and being good at judo despite stop practicing it regularily for years, while she had throw all of it away in order to dedicating only to her judo career.

She's easily excitable and seemingly loves gossips and romance. Her main attribute are her almost superhuman-level physical feats, having been shown capable of overpowering a larger opponent with one hand, moving without been heard nor seen by anyone almost like if teleporting and going through multiple consecutive fights without even breaking a sweat.

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.

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.
