Orihara

"We keep on fighting and fighting, then finally during one match, I lost. It wasn't even by a slim margin, I was totally overwhelmed. Honestly, I don't think I can ever beat her again."

- Nagatoro on Orihara

Orihara (折原) is a background-turned-minor character of the Don't Toy With Me, Miss Nagatoro manga series. She is a high school student and a schoolmate of Nagatoro and her friends as well as the main rival of the protagonist, albeit she's totally oblivious of it and always extremely friendly as well as utterly nice toward her. Orihara is an energetic, positive, joyful and passionate girl whose constant hard-work and nearly superhuman skills have made an Olympic team candidate.

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".

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.

Early life
Orihara was born in, , no information about her family or her home life are given. 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.

Trouble at the Judo club arc
Few weeks later, while practicing judo until late evening with Nagatoro and Gamo-chan, Orihara saw when Shikki, a girl who considered Nagatoro to be "a quitter who half-assed her life" and was always very harsh to her, challenged her to a match eventually hurting her right arm while Senpai was watching. Afterward, she got got worried due to Nagatoro's injuried wrist, offering to take her to the infirmary despite the latter insisting it was nothing serious; then, after Shikki further insulted Nagatoro and Senpai stood up to her hushing the girl, Orihara and Gamo-chan watched his deed, quite pleasured.

Later, Nagatoro thanks both of her friends for having helped her, as well as her rival right before remembering her they will soon have a match, to which the latter smiled wholeheartedly.

The evening after they came back from the trip, Orihara and Gamo-chan oversaw a friendly sparring match between Shikki and Nagatoro, commenting on how fast the latter was growing.

The following day, after the responsible of the judo club told the members that the coach they had requested has had an emergency and thus couldn't be at their training camp, she and Shikki pointed out having a coach would be indispensable, which lead Nagatoro to propose her siblings as replacements. Later on, before departing for the training camp, Orihara was overjoyed to have Misaki and Taiga Nagatoro as coaches, Sakura and Yoshi as special managers and the art club doing their training camp with them; then she travelled with them to the, where they began the training camp and she enthusiastically follow Misaki's and Taiga's instructions, as well as having a sparring session with Nagatoro on the evening, quickly defeating her. At the end of the first day of training camp, Orihara and the rest of the girls at the and, after they talk about Nagatoro having to loosen up a bit, she proposed to have a chat with her, before Gamo-chan telling her she would have the opposite effect on the girl.
