Misaki Nagatoro

"You came all the way out here. So I was going to tell you anything you wanted to know, every little detail about her... aren't you interested...?"

- Nagatoro's sister to Senpai

A girl whose surname is Nagatoro (長瀞), is a minor character of the Don't Toy With Me, Miss Nagatoro manga series. She is Hayase Nagatoro's older sister and likes to tease the latter despite caring and loving her deeply. After realizing about the true feelings between her little sister and Senpai she decide to help their budding relationship.

Her first name is currently unknown and Senpai only refers to her as "Big Sis-Toro" (姉瀞).

Appearance
She is a beautiful, shapely and yet short statured young woman with medium length, straight black hair that falls on her forehead in a thick fringe. She has a relatively light skin, and large, expressive and yet somewhat tired-looking dark amber-maroon eyes, with an attractive mole under the left one. Her ears are not pierced and she does not seem to wear earrings or any kind of jewelry. The girl is very similar to her younger sister in term of physical shape, sharing her lean, athletic, slender and flexible physique albeit with a larger bust size due to being a young adult rather than a teen. The girl sports almost always a wide, kind and sweet smile displaying incisors slightly pronounced than average. Also, she has her sister's same tendency to widen the pupil of just an eye whenever she grins.

She typically wears sport clothes, sweatshirts, tight pants and sneakers.

Personality
Nagatoro's sister is a calm, cheerful, easy going and level headed girl with a bit of liking for teasing, just like her little sister Hayase, although at a very lower level. She loves to joke and is very friendly, when first introducing herself to Senpai she makes him believe she would have called the police and have him arrested for trespassing into her home, only to reveal she was merely kidding and then inviting him inside. A very mature and responsible girl, she behaves like an excellent hostess to Senpai and take good care of her sister, to whom she's very protective and caring to. Moreover she has proven to know her little sister so well to easily "manipulating" her, making her "dance in the palm of her hands" - much to Senpai's astonishment - even to the point to talking her around or scolding her about her manners when she didn't behave, showing to be very polite and well-mannered. She is very excitable, inquisitive and honest, despite this blunt attitude of hers sometimes create awkward situations being a source of embarrassment for Hayase, albeit mostly unintentional.

It's also shown that Nagatoro's sister could emanate her same intimidating aura of her younger sister, and, whenever this happens, she is depicted with hellishly shadows on her face and disturbingly huge eyes pupils.

As the "cool big sis" and reference figure to Nagatoro, she's a sort of confident to her; Nagatoro told her about Senpai more than once, indirectly making her aware of how she felt about him as well as their "erotic" interaction. Although she somewhat likes to tease her little sister and sometimes embarassed her, treating her like if she was still a child, she does love her deeply, is rather protective of her regard and willing to help the relationship between her and Senpai, often offering the latter to tell him more about Nagatoro if he wanted to.

In stark contrast with the maturity she usually display, the girl seem to have a habit of eavesdropping and very little sense of personal space.

Early life
The girl was born in, the older daughter of the Nagatoro family. She has a close relationship with both her brother Ichirō and younger sister Hayase, while her parents are middle class that often work late. She grew up in a house in the suburbs right in front of a park, under a 7-eleven; as a kid she went every year to the summer festival with her family, enjoying the fireworks contest at the beach.

Being at least eighteen or older, she is likely to be an university student.
