Mrs. Hachiouji

"Oh dear, that's terrible. What should I do...? I have a business trip today..."

- Mrs. Hachiouji to Senpai

Mrs. Hachiouji (八王子) is a background character of the Don't Toy With Me, Miss Nagatoro manga series. She is the mother of Senpai, a caring woman who loves her son very much but is often away from home due to her very demanding job.

Her first name is currently unknown.

Appearance
The woman is a very tall, slim and lean middle age lady with medium-length, curly, "fluff-like" brown hair parted to the left with a fringe. She has an extremely pale and delicate complexion - much like her son's - and sharp, thin brown eyes, albeit the left one is slightly covered by her fringe. The woman has a well-proportioned and dry physique with medium bust size. Also, she has very wide smugness when acting inquisitively to her son.

She is always seen wearing business attire, with shirts, turtlenecks, stockings and tailleurs, however, on her days off she was shown wearing comfortable sweaters and tight pants.

Personality
The woman is a very caring, sweet and dedicated individual who is very loving toward her son despite being also extremely responsible and hard-working, to the point she is often torn between her work and family commitments. She tends to treat her son as if he was still a kid and, according to him, is also very calm and patient, to the point of never raising her voice or having ever yell at him.

An extremely intelligent and inquisitive individual, the woman managed to deduce exactly what kind of relationship there was between her son and Nagatoro just by asking him a few simple questions as well as guessing Nagatoro's true nature, describing her as "adorable", despite having just a very brief encounter with her.

She has a habit to start all of her sentences by saying "My, my" or "Oh, dear".

Early life
The woman was born in, , where she met a man named Hachiouji, married him and had a son, Naoto. Both the woman and her husband are managers who often leave their son alone due to their job, making him a. Her family lives in a house in the suburbs right after a tunnel at the left of the first intersection past the public park.

First name arc
After her son informed the woman that he caught the flu, she began worrying for him and considered cancelling her business trip to take care of him; however, knowing the importance of her job, the boy told her that he would have been fine and that it was "nothing serious", prompting her to leave promising she would have hurried back. However, a few hours later she sent her son a message asking if he was feeling better and informing him she would have been home late. After coming home late, the woman noticed a girl's loafers at her porch and deduced her son had a friend over. The girl in question run out of her son's room and ran into the woman in the living room, being too embarrassed to say anything the high schooler left the woman's home with minimal explanation without even introducing and asking forgiveness for her intrusion. The following morning, her son felt better and the woman asked him who was the "adorable girl" who she met the previous night and took care of him while he was sick, assuming she was his girlfriend, thus leading the boy to blush and reply that she was simply a kōhai of his.

New Year
On New Year's Eve, the woman looked at the traditional TV special with her husband and son, then, after the latter received a phone call from Nagatoro, she asked intrigued if it was "a friend" of his, likely guessing it was the kōhai she previously met.

Trivia

 * The woman is the second parent of a main or recurring character to have ever appeared, after Sakura's father.
 * However, due to Sakura's father having appeared in Side Story 9, she is actually the first parent appeared in the main story.
 * Given that she seems to be almost as tall as her son (176 cm) her height could be estimated as approximately 170 cm.
 * The reason why her eyes are not shown is unclear since the in-universe reason of said treatment for some characters is Senpai's defense mechanism that made him unable to remember the faces of those who bullied him or - by extension - everyone he first meets; however none of this can be applied to his mother, especially since their relationship was shown as quite close.
 * The author later corrected this by drawing the woman's eyes in the physical release of Chapter 66 in Volume 9.
 * She is the adult characters with the most "page time" and speaking lines in the manga.
 * In the manga, despite sharing her son's curly hair, Mrs. Hachiouji had a completely different design and their hairstyles were very different, however in the anime she's depicted as pretty much identical to him.
