The Campus SKET
Hime grew up in Osaka and started playing field hockey in primary school, continuing through junior high. When she was 14, her family moved to Tokyo due to her father's job and Hime found herself alienated from the classmates at her new school. This led her to feel uncomfortable and purposefully isolate herself. When she joined the school's field hockey team, she met with opposition from its regular players but also encountered Arisa, who became her first friend at the new school. Thanks to Arisa's presence and effect on her, Hime opened up to her classmates and found them opening up to her as well. One day, she saw Arisa leaving with a group of delinquents and began to fear that her friend was being threatened. These suspicions were further confirmed when she saw Arisa handing an envelope of money to the delinquents' leader, Kyōko.
When confronted, Arisa first claimed that nothing was happening but Hime persisted - declaring that Arisa's kindness and femininity could be perceived as weak, and thus that she would protect her. Arisa broke into tears, saying that Kyōko had told her to come that evening with a large sum of money. That night, Hime went with Arisa and withstood Kyōko's beating to ensure her friend's safety. However, when the envelope Arisa had given fell from Kyōko's pocket during the fight, Hime noticed that it had been labeled with Kyōko's first name, implying a sense of familiarity. She realized that Arisa wasn't being bullied or threatened at all, and Kyōko declared that Arisa had been paying her group to act as bodyguards. Hime couldn't understand the turn of events, and her friend explained. Arisa had been bullied in the younger grades and didn't want to stand out, so the safest place to be was right behind the strongest person in school. Being a victim was only an act so people wouldn't realize the truth. Arisa then snapped at Hime for having called her weak and Hime's emotions boiled over. Using her field hockey stick, she severely beat the group of delinquents, like a demon. The story of the fight spread quickly and once again Hime found herself isolated - but this time, feared as well. Other groups started targeting her to fight, but she beat each one. Eventually, she became known as a legend: the demon princess "Onihime."
In her final year of junior high, Hime decided to apply to a high school far enough away that no one would know of the name "Onihime." After enrolling in Kaimei High School, she kept to herself and firmly held the belief that she didn't need friends. The rumors of the "Onihime" had reached even there, and she decided not to stand out and to complete her school years without fuss. Yet after an amazing throw during a fitness test, she was approached by her class representative, Chiaki, to join the softball team. Despite Hime's efforts to remain isolated, Chiaki persisted in trying to draw her out of her shell. Soon, she found herself with a second attachment, a classmate named Yūsuke, who noticed when she accidentally brought her old Poppman cap to school one day. The more Chiaki and Yūsuke persisted in being her friend, the more Hime grew used to their presence.
When Chiaki was threatened by two men who claimed she had dented their car with a baseball, Hime ultimately came to her rescue. However, her weapon broke and it was only Yūsuke's timely arrival which prevented the two girls from meeting a horrible fate. Once freed, Hime easily defeated the men who then recognized her as the "Onihime." Certain her new friends would abandon her upon finding out, Hime prepared herself to be alone again, but Chiaki and Yūsuke refused to leave her alone. The latter then asked her to form a campus support group with him, declaring that he needed her strength. Having finally found a place where she was accepted, Hime was able to cry for the first time in years.
Himeko has blue eyes and shoulder-length blonde hair that flips up at the ends. She can almost always be seen with a Pelollipop Candy sticking out of her mouth (when she was known as the "Onihime," the lollipop stick was mistaken to be a cigarette). Himeko wears the basics of the Kaimei school uniform (a white shirt with a white sailor collar, a red collar ribbon and a blue skirt) with the addition of a black choker and high heels. On one wrist she wears a thick black studded bracelet and on the other is her Sket Dan wristband.
Prior to the events which led to her becoming known as "Onihime," her hair was black and fashioned in a similar hairstyle to Bossun's. As the "Onihime," she had longer blonde hair parted away from her forehead and tied back in a ponytail.
Despite being naturally aggressive and a little cranky, Himeko tries to maintain as positive as Bossun, even if sometimes she doesn't succeed. Anyway, she has a good sense of humor before losing the patience, which, indeed, is little. Hime tends to be violent when something goes wrong and, indeed, in many cases the violence is her first choice to fix the problems.
Anyway, Himeko has a good heart and, like her companions of Sket-dan, is determined to do whatever it takes to help other people. It also appears that takes more seriously the everyday affairs, or at least more than Bossun and Switch.
Hime is loyal and admires Bossun, although she often hits or rebukes him. This is because she feels that she owes him much. Himeko is rude, but feels a special affection for the little and "cute" things, and sometimes her maternal instinct comes out easily. By being originally from Osaka, Hime uses some different words or phrases to other characters, although this is only noticeable in a few jokes or situations.

The girls decide to tell the information to their boss, Momoka.
Chiaki tells the Sket Dan that there's a rumor the Onihime is causing trouble again. But it wasn't Himeko, since she's not the person she used to be. On her way to home she's confronted again by the trio. Unfortunately for her, she mistook her Cyclone for Switch's Reality Maji's cynical stick, making her vulnerable. Inui and her gals knock Himeko out by covering her mouth with tissues laced with anesthesia.
When she awakens, she met their gang, Momoka, who claims to be the legendary Onihime. When Himeko's phone rings, Momoka picks it up and chat with Bossun.

After Switch unties her, Himeko easily defeats Momoka with sheer intimidation using her Cyclone to smash the ground. Momoka and her gang realize Himeko is the real Onihime and submit to Himeko. It turns out that Momoka had always been a big fan of the Onihime legend, and now she and her group have begun idol-worshiping Himeko, as they call Himeko with "Nee-san".

After some contemplation to find an answer that won't hurt Saaya's feelings, Himeko (as Bossun) replies that Himeko is a friend. Later that night, Himeko and Bossun sleep together in Chūma's room. Himeko informs Bossun about Saaya, and she asks him what he felt about Saaya. Bossun replies that he only thinks of her as a friend. At the end of the trip, Chūma has Himeko and Bossun take the drug.
