Plot Tousuke Rokudou, a first-year student at Amori High, a school attended mostly by delinquents, wants to live a peaceful life with his friends. However, this seems to be impossible because he is constantly bullied by his delinquent classmates. When Rokudou and his friends become desperate, Rokudou receives a mysterious package from his long-deceased grandfather. Inside lies, a priest's uniform and a mysterious scroll passed down through his family since the Japanese Heian period, said to hold a technique warding off demons and evil spirits. In hopes of combating his delinquent tormentors, he undergoes the ritual to activate the scroll's power. The scroll initially seems to have no effect on his school's delinquent population, but once a bully tormenting Rokudou is stopped by a delinquent girl, Rokudou's friends realize the technique's power does not ward off evil spirits and monsters, but rather makes the user popular with bad women. After realizing the potential of his newfound ability, Rokudou vows to become stronger and use his power to achieve his dream of having a peaceful school life, unwittingly acquiring a harem of delinquent schoolgirls along the way.

Characters

The main protagonist of the series, Tousuke Rokudou is physically weak and cowardly attending a school filled with delinquent students. He and his two friends live in constant fear and is regularly bullied, leading to the trio venting their frustrations in private in the school's restroom. Upon receiving a scroll from his grandfather, Rokudou gains a special pentagram mark on his forehead. Rokudou's ancestors used this spell to exorcise oni, but in the modern day, the spell causes any "bad girl" to instantly fall in love with him once he makes eye contact with them. His school life drastically changes as not only is he thrust into the delinquent culture of his school, but he encounters several girls, each one presenting a new problem. He helps rehabilitate most of the girls focused on, each one genuinely falling in love with Rokudou or becoming a close ally. While Rokudou refuses to fight in the beginning of the story, his tenacity and refusal to run away has garnered respect from his former bullies. Later, he learns kung-fu and has learned most of its fundamentals from Ling Lan.

Ranna Himawari is a young girl with a notorious reputation as a Sukeban wielding a Bokken, often described as a "monster" for her sheer strength and brutality. She is the first main girl to fall in love under Rokudou's spell. Generally, Ranna does not speak or express much emotion other than emotional distance unless Rokudou is around, but tolerates his friends. Around Rokudou, she is extremely bubbly and smiles. She will not hesitate to stop and protect him when he is in danger, but will respect his wishes as she did not step in between Rokudou and Iinuma's fight when he asked her to and only attacked once he asked for her help. As a child, it is revealed that Ranna was adopted by an elderly couple because someone had left her at their doorstep. To their shock, even as a baby, she had a horribly demonic visage. Growing up, Ranna was nothing short of a demon for her cruel actions, even brutally dragging a priest tied to her tricycle. Thanks to special beads from the same priest, she became more demure, but reverted once they shattered. Years later, Rokudou would receive a pair of these beads, though now they completely pacify her, causing her to deeply fear them. Her surname, Himawari, means Sunflower in Japanese.

Most likely nicknamed for military beret and camouflage in his outfit, "Colonel" is one of Rokudou's friends from the beginning of the series. He shares Rokudou's dream of living a peaceful school life, free of his delinquent bullies. Along with Rokudou and their friend "Manager", he huddles in a bathroom stall during school hours to vent his frustration with the way his life at Amori High is. He is the first to theorize that the ability Rokudou received from the scroll was that of making him popular with "bad girls." He frequently assists with conflicts Rokudou is involved in, along with his friends.

Most likely nicknamed for his formal attire and businesslike demeanor, "Manager" is one of Rokudou's friends at the beginning of the series. Like "Colonel" and Rokudou, he too, wishes to lead a peaceful life at Amori High and is constantly bullied by his delinquent classmates. Like "Colonel", he notices that Rokudou is popular with "bad girls" and tags along with Rokudou and his friends when he gets into conflict with delinquent gangs.

Iinuma was the main bully of Rokudou and his friends, subjecting them to cruel pranks at their expense. After Rokudou awakens his powers and inadvertently affected his girlfriend, Tsubaki, he challenged him to a fight. Despite being overwhelmingly stronger than him, Rokudou refused to run and took an intense beating before he asked Ranna to intervene in the fight. Impressed by his tenacity, Iinuma befriends Rokudou and becomes one of his closest allies, eventually becoming close enough to know about his power. He is one of the strongest fighters in Amori high, only behind to Ranna and Sayuri in terms of raw strength. Iinuma has a love for both ramen and motorcycles, desiring to one day own a mobile ramen stand. He loves customizing his motorcycle, but tends to make them overly gaudy and flashy with unnecessary "upgrades."

Originally one of Rokudou's many bullies, Tsubaki is Iinuma's girlfriend. After she falls under the spell of Rokudou's powers, she becomes remorseful for the way she treats him, and apologizes to him while in the bathroom. Her attention to him draws the initial ire of Iinuma, though after the two become friends, Tsubaki regularly hangs out with Rokudou and his friends. She does not react to Rokudou's power anymore. Her name comes from the Japanese word for Camellias, tsubaki.

With the appearance and demeanor of an elementary school, Sayuri is often mistaken as one despite being a student at Aomori High. Despite her petite appearance, Sayuri is the bancho of the school having built a reputation as its strongest physical fighter. She originally targets Rokudou for his inexplicable ability to become popular with the female students of Amori High, but when she begins her attack on him, she becomes enamored with him due to his spell's power. Rokudou thus becomes her first love. Through the influence of Rokudou, she reforms and reintegrates back into school life and helps him achieve his dream of a peaceful life by means of her powerful influence over her classmates. She has since become a powerful ally of Rokudou and one of the first to jump to his aid when matters involving outside delinquents befall him or Amori. Her name, Sayuri, means Lily in Japanese.

Passionate about police work and motorcycles, Azami Himeno is the third major female character to become enamored with Rokudou. Initially assumed to be sweet and feminine, she loves riding motorcycles. She holds a grudge against biker gangs, who she violently beats while mounted on her motorcycle. She acts like a vigilante, warning citizens about traffic safety and taking down those she perceives to be evil delinquents on the road. She is the only one of the main girls to not attend Amori High. Her forename is a play on the Japanese word for Thistle, azami.

Minami is the fourth girl Rokudou rehabilitates who has the general appearance as a bat prior to meeting Rokudou. Originally a loan shark who had scammed out money from hundreds of people, her latest being Manager's parents. In a twist of fate, she meets Rokudou and falls victim to his power and begins lavishly spending her money to impress him. She also gives him advice on how to help Manager stop his parents' loan shark, ironically putting a halt to her own plans. When she discovers Rokudou's role, she becomes despondent when her allies betray her and steal her remaining money. After hearing his plight, she gifts the money to Jin. She later enrolls Amori High the next school year as a first year student. Her surname in Japanese is based on the Japanese Marigold Bush.

When Rokudou and his male friends attempted to search a remote mountain for a temple that supposedly had the beads that could pacify Ranna, Rokudou encountered Ling Lan who had found them while they were lost in the forest. Upon first glance, she was serene, even described as a "goddess" by Rokudou and his friends. In reality, she too was wearing the very beads Rokudou had been searching for. Upon returning to the temple, she had inadvertently removed the beads wanting to give it to Rokudou to help him, but in the process had removed its effects and becomes the fifth girl. Ling Lan is a foul mouth, brash, and fight-seeking girl and a master of kung-fu. While immune to Rokudou's spell with the beads on, upon its removal, she too fell under his spell. She teaches Rokudou the basics of kung-fu and after a week, he had grasped enough basics to become a competent fighter and she falls in love with him. After the priest decided to depart on a pilgrimage with the remaining rehabilitating teenagers, Ling Lan enrolls at Amori High school as Rokudou's underclassmen in his second year. Her name in Chinese means Lily of the Valley.

Adopted daughter of a female crime boss, Sachiyo has the power of foresight by looking into the eyes of another person. Her clairvoyance ranges in time, but in most instances she uses it to see into the near future. It was initially believed that she was sent to Amori High School as a new first year student by her mother to extort the student body using her power. Unbeknownst to her, her mother intentionally sent her there to meet Rokudou and use his power to reform her into a normal girl, making her the sixth girl. Upon falling to his power, she loses her foresight, becoming clumsy as a result and slightly depressed by the loss of her own power. Her mother's associates kidnap her as they need her power to maintain their hold on the criminal underworld. Her surname in Japanese, Sakura, means Cherry Blossom.

Onishima Alliance (鬼島連合)

Leader of the Onishima Alliance. Though he is polite, he can also be extremely intimidating. Like Rokudou, he was once a timid and extremely fearful of other people, resorting to bribing stronger individuals to protect him. He eventually joined the Onishima Alliance in order to be surrounded by strong individuals. After Ranna easily defeated the Alliance on her own, he fell in love with her strength and desired to have her join the alliance by gathering strong individuals to refortify its ranks, taking over as leader of the Alliance in the process. Despite being a coward in the past, he has become strong enough to fight off Rokudou and his friends all on his own. Despite failing to recruit Ranna, he soon realizes that he has become strong and his allies in the Alliance genuinely admire him for his strength and acknowledges his worth without any bribe to validate him.

Holding Rank 1 in the Onishima Alliance and is the strongest member of its alliance after Douji. She has an interest in strong men, but she shows her feelings through acts of sadism, reveling in breaking their spirits. Under Rokudou's power, she sees him as an exaggeratedly strong man that progressively intensifies during their fight. Rokudou "defeats" her after rescuing her from falling out a window, causing his power to exaggerate his appearance so much that she faints in bliss. In the aftermath of the fight between the Onishima Alliance and Amori High, she leaves the Onishima Alliance. Part of her surname, Yashi, means Palm Tree. Sumire Triplets
