Hitagi, a main female character of Bakemonogatari, is a weak-looking girl with an "incurable disease." She is in the same class as Koyomi, but he has almost never heard her speak. When she was in the first year of high school, she encountered a mysterious crab, after which she became nearly weightless. Ever since then, she has avoided contact with everyone else, threatening everyone who discovers her secret. She jokingly labels herself as a tsundere and speaks with a sharp tongue.

Mai Sakurajima (桜島 麻衣, Sakurajima Mai) is the main character of the Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai series. She is a notable actress/model and a third year at Minegahara High School, the same school as Sakuta Azusagawa. Mai is a serious individual, especially around Sakuta Azusagawa. She is very sensitive, polite, levelheaded, helpful, and kind. She isn't harsh by default, but she can become easily annoyed and come across as somewhat snappy or violent especially to Sakuta. Mai tends to ignore and stuff down unpleasant feelings rather than deal with them. Sakuta often points out that she is "dishonest", often lying about her feelings. Despite her snarkiness, she's pure-hearted and even shy around Sakuta's jokes. Mai is also very intelligent; she's implied to have very good grades and even helps Sakuta study at one point. Mai found early fame as a model for television, magazines, and books due to the fact that her mother ran a photographing agency. While she did enjoy her job as a model in the show business, the pressure of being in the public began to take its toll on her. After being tricked and forced to participate in a swimsuit photoshoot by her mother in her early school years, Mai realized she was simply being used as a tool to make her mother easy money and took a hiatus from acting as a way to get back at her, deciding to attend highschool. However, because of work commitments made prior to her decision to go on hiatus she wasn't able to attend school until half-way through her first year. By then, social circles had formed, making her the "odd one out" and causing her to be isolated. As a result, the student body didn't know how to deal with her; While they had no reason to bully her, they also feared associating with her would cause themselves to be isolated as well. Two years and several months since beginning her hiatus, Mai went to a library wearing a bunny costume to see if anyone would notice her. She then came across a boy named Sakuta Azusagawa, who was the only person in the building able to see her. After introducing themselves, however, Mai ordered Sakuta to forget about her.
