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. She's described as the type who enjoys spoiling her little sister. Yet she has also proved to know Hayase so well that she managed 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 when she acted stubbornish 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. According to her little sister she tend to "run her mouth off". Also it's insinuated that she that she may be quite vain.

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 all over her face and disturbingly huge eyes pupils, making her look like a ghostly entity.

As the "cool big sis" and model figure to Nagatoro, she's a sort of confidant 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, or teasing her about romance, she does love her deeply, is rather protective of her and willing to help the relationship between her and Senpai, often offering the latter to tell him more about Nagatoro if he wanted to. It is also strongly implied that Hayase actually looks up to her, trying to emulate her attitude and having learn how to "tease" boys from her, as well as often going to her for advices.

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. She can also be quite careless, since she forgot to close the house front gate before going shopping.

After Hayase began attending high school she started to talk a lot to her about "her Senpai" and their interactions, leading the young woman to realize about her sister's crush on him.

First name arc
One day, after her little sister get a flu, she stayed at home with her and took care of her. In the afternoon, she went to the kombini to take a pudding for Hayase while she was taking a nap, accidentally leaving the front gate open, and when she came back home, the young woman noticed a boy in the front yard; recognizing him as Senpai she pull a prank to him pretending she mistook him for a thief, before introducing herself as Nagatoro's sister and inviting him inside. After checking on her sister and discovering she was still sleeping, the young woman offered Senpai some snacks and revealed to him that her little sister talked a lot about him. She also asked if there's anything he wanted to know about her, stating that she would reveal him whatever he want regarding her sister. Before Senpai could make his question, Nagatoro entered the kitchen yawning, with messy hair and a comfy pj, blushing in embarrassment after discovering that he was there.

Embarassed, the girl immediately went to dress and do her hairs, scolding Senpai for not having called nor warned her before coming to her house, to which he replied that he sent her a text, although she yelled back at him that she was sleeping. After telling her little sister not to be so angry, the young woman acted as a pacifier preparing her little sister a special marlowe pudding with fruit and cream to calm her down, saying that they should all sit and chat a little. However feeling ashamed, Nagatoro asked Senpai to came to her room and forbid her sister from entering. Regardless of this, she later entered the room to bring them something to drink and caught her little sister feeding Senpai with a spoon commenting the boy does indeed seem interested in "every little detail" of her little sister. Blushing vividly, Nagatoro sent her sister out of her room, then she asked Senpai what does she meant by her last sentence.

Few minutes later, having eavesdropped on her sister and Sanpai's conversation regarding the boy wanting to know Nagatoro's first name but lacking the courage to asking it directly, she stormed once again into the room calling her little sister "Hayase" and bringing the photo album of her primary school years in order to show it to Senpai. Regardless of Nagatoro yelling her to getting out of her room, the young woman continued to show embarassing picture of "little Hayase" - that she deemed "cute" - to Senpai.

Few days later, Senpai caught a flu and Hayase visited him at home calling her sister to inform that she would have been at home later than usual due to wanting to nurse him; it's implied that she teased her little sister about the romantic meaning of said gesture, since the girl blushed vividly, hushed her and quickly hang up the phone.

Christmas
Right before Christmas Eve, during snack time, Hayase meekly asked her for advice regarding what to buy to someone for Christmas. Delighted for the question, and guessing the reason, the girl asked her younger sister if it was intended to be a present for "someone special", which Hayase denied embarrassed, causing her older sister to tease her that if it wasn't a special person then consumables like snacks or bath salt would have been fine, since those things got used up and wouldn't get spoiled. Hearing that she should give something that would "be gone", Hayase got sadden, but she quicly cheer her up saying that she might give something that would last as a Christmas gift, suggesting her to take something "he" would use everyday. Overjoyed, her little sister thanked her and asked the girl if she also would have liked to receive something that would last as a Christmas gift, which the she responded positively right before joking about giving to her sister a life-size doll of herself for Christmas. Listening to her older sister advice, eventually Hayase got Senpai a scarf.
