Hayase Nagatoro | Workout Snack

Hayase Nagatoro is one of the two main characters of the Don't Toy With Me, Miss Nagatoro manga series. She is a high school student who likes to tease and bully. Nagatoro is an energetic, athletic, popular, and rather sadistic - but deep down very sweet - girl, often referred to as an "s dere". She is part of a "cool kids" clique together with her friends Gamo-chan, Yoshi and Sakura, and is a member of the swimming club, despite also having a huge passion for martial arts such as muay thai, boxing, capoeira and especially judo which eventually lead her to join the judo club as well, becoming one of its aces.

Her friends affectionately call her with the pet name "Hayacchi"

Nagatoro is an attractive, petite, and short-statured high schooler with long, straight black hair pinned to the right side with a pair of white hair clips. She has brown skin with noticeable - though sometimes inconsistent - tan lines in the shape of her swimsuit, and large, expressive amber-maroon eyes. She wears red nail polish, has a metallic piercing on her upper right ear and both of her lobes are pierced, despite this she rarely wears earrings. Nagatoro has a lean, athletic, slender and very flexible physique with a modest bust size which she is often ashamed about despite being - considering her size and build - pretty average sized. Nagatoro is rarely seen without a sadistic, cocky, smirk that often displays her very prominent canines and has the tendency to widen the pupil of just an eye whenever she grins.

She typically wears her school uniform consisting of a white button-up shirt (whose sleeves and collar she never keeps buttoned) and a navy blue skirt completed with a pair of sneakers and no 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, black thigh-high stockings, loafers and occasionally a blue blazer. She is also often seen wearing the light blue and white swimsuit of her club and her judogi.

When not at school she usually sports a simple, practical, or tomboyish choice of clothing unlike most of her friends; however, she has proven to know how to relatively dress up if needed.

When she's out exercising, Nagatoro wears a sporty outfit consisting of a skin-tight, skimpy top and short shorts. She also has her hair in a ponytail. This outfit is designed to be revealing and athletic, leaving her midriff exposes. The color of this attire consist of a dark-purple sports bra and matching dark-purple bottoms.

Nagatoro comes off as an energetic, cheerful, sarcastic, flirtatious, prone to fast-talking, and moving individual with a sadistic streak. She likes to bully and finds joy in teasing, however, in early chapters her antics could easily be described as "sadistic". Nagatoro is very much a tsundere.

She is very good friends with Yoshi, Sakura, and especially Gamo-chan, who could be considered her best friend, despite their similar and often competitive personalities sometimes putting them at odds in a sort of friendly rivalry. Also, Gamo-chan loves to tease her in order to make Nagatoro admit her feelings for Senpai and bring them closer, causing pranks that sometimes led the two to resort to near-physical violence, despite that they seemingly always made peace rather quickly every time they fight. Moreover, judging by their friends' reactions whenever Nagatoro and Gamo-chan butt heads, it's not wise to make them mad, implying that they both have a temper warranting fear. Nevertheless, the two girls genuinely loves one another and, under their harsh personalities, are very supportive and caring to each other.

Although very popular among boys, with several of them often attempting to hit on her or her friends, she always rejects them and shows herself to be quite standoffish while talking to them.

It's also shown that Nagatoro is a sweeter and more empathetic person than she lets on. Despite very frequently making sexual jokes, she is very nervous and sensitive about sexuality.

Nagatoro has a complex for her bust size and appears to be very self-conscious as well as jealous and possessive. Due to her jealousy since she is the least buxom among her friends, her teasing is somewhat just a front, a coping mechanism to mask her insecurities and inner nervousness.

She is also very athletic, loves the beach, is a fantastic swimmer and a superb skier as well as having a huge passion and proficiency in various styles of martial arts.

Apparently, Nagatoro doesn't like shoes, as she rarely wears socks and is frequently barefoot when she can get away with it.
