Kyō Kara Ore Wa!!

Takashi Mitsuhashi (三橋 貴志, Mitsuhashi Takashi)

Voiced by: Yasunori Matsumoto

Main protagonist, 181 cm tall. At the beginning of the story, he was around 15-16 years old. He gave up his ordinary school life and decided to "become a delinquent from today on" (thus the title of this manga), after moving to his new home in Chiba. Being a very athletic person, he used his talent for the sole purpose of brawling and actually becomes a real delinquent. To make his appearance more noticeable, he dyed his hair blond. Being the most self-centered person in this manga, his own safety comes before anyone else's, he often sacrifices his "friends" for his cause. He is greedy and cunning. Although, beneath his devilish personality lies a softer side, which shows from time to time, especially when he is angry. His fighting style is based around his speed, as he often dodges most attacks, becoming surprised whenever he is forced to block due to being faster than most of the people he encounters. His love interest is Riko-chan.

Shinji Itō (伊藤 真司, Itō Shinji)

Voiced by: Hideyuki Hori

Main protagonist, 180 cm tall (205 cm including his hair). A complete reversal of Mitsuhashi, Itou's the kind of righteous person fighting for justice. Just like Mitsuhashi, Itou got transferred to Nan high's first year. Like his personality, his fighting style is also the opposite of Mitsuhashi's; he's incredibly tough and often stands up from any beating, even in the most bleak of situations. While he may be as strong as Mitsuhashi, Itou is beat up much more often than Mitsuhashi due to often sacrificing himself to protect others as well as fighting fair in unfair situations or against numerable opponents. Due to his help, he wins the affection of Kyouko-chan, an ex-delinquent girl, at the start of the series.

Riko Akasaka (赤坂 理子, Akasaka Riko)

Voiced by: Fumie Kusachi

Main heroine, the only daughter of the Akasaka style dojo. Originally she visited another senior high school than Mitsuhashi and Itou, but ultimately decided to transfer to Nan high instead to repay Mitsuhashi's favor. Behind her pretty looks lies someone pretty skilled in Aikido; she can handle most delinquents on her own despite her small body size. While she used to be very popular at her old school, in Nan high she is initially considered "weird" because of her constantly hanging out with Mitsuhashi. As the manga goes on, she spends more and more time with Mitsuhashi, and he sometimes intrudes in her home/dojo, often irritating her father, who also seems to get used to Mitsuhashi. She is romantically interested in Mitsuhashi and is one of the people close to him who know his softer side. She is the only person who refers to Mitsuhashi as "San-chan" because 三 (mitsu) is also read as the number three (san).

Ryō Tanaka (田中 良, Tanaka Ryō)

Voiced by: Masami Kikuchi

Student of the Akasaka style dojo, and in love with Riko. 160cm tall. His sense of justice is as strong as Itou's, and he is a modest person who is willing to help people in need out whenever he can. Despite his initially weak body, he never backed down to any delinquent's threat. He was transferred to Nan high together with Riko, which is why everyone calls him "Ryou-kun" like Riko does. Surprisingly, he can hold his own against Mitsuhashi.

Shūichi Takasaki (高崎 秀一, Takasaki Shūichi)

A handsome transfer student from Saitama, around 180 cm tall (he has short legs though). He originally transferred to Nan high to avoid trouble at his home place of Saitama during the Kitagawa incident, and was quickly at enmity with Mitsuhashi because of his righteous nature, even more so than Itou. When he first appeared, he seems to have an equal charm towards girls as Itou, which only grew when he defeated the duo in a match of Judo. At the end of the Kitagawa incident, he got to know Mitsuhashi's true nature and became friend with them, aiding them multiple times in battle in order to repay their favor. A running gag in the manga, is whenever Itou is doing something emotional with Kyouko, he appears and witness an embarrassing scene.

Naoya Sagawa (佐川 直也, Sagawa Naoya)

A delinquent from Nan high, who quickly became Mitsuhashi's and Itou's lackey and informant due to his nature "always succumbing to the circumstances". Even though he is no strong fighter, people respect him for the sole sake of him being able to call for Itou and Mitsuhashi's help at any given time.

Keiichi Izawa (伊沢 圭一, Izawa Keiichi)

A delinquent and good friend with Sagawa, also being considered a lackey of Mitsuhashi and Itou.

Megumi (メグミ, Megumi)

Riko's girl friend at Nan high, with lots of screentime, but very few times they refer to her with her name.

Yūichi Sakakigawa (榊原雄一, Sakakigawa Yuuichi)

A junior with passable strength, at least 2 years younger than Mitsuhashi. Mitsuhashi gave him the nickname of "pisshead" because he once peed on them while they were trapped in a well. When introduced, he is an overconfident middle school student and tries to defeat Mitsuhashi. However, he soon gains immense respect for Mitsuhashi after witnessing his strength and looks up to him. Mitsuhashi regards him as a bud despite his young age.

Kyōko Hayakawa (早川 京子, Hayakawa Kyōko)

Voiced by: Yumi Ichihara

The second heroine beside Riko. Although a former Yankee girl, she's very beautiful and guys try to hit on her on occasion. She becomes Itou's girlfriend near the beginning of the series after he takes a beating in order to rescue her from a group of thugs. Her parents approve of her dating Itou and are just grateful that she isn't dating Mitsuhashi.

Katsutoshi Imai (今井 勝俊, Imai Katsutoshi)

Voiced by: Yūsaku Yara

Beni high's Banchou, the eldest son of four brothers, 192cm tall. Despite his incredible strength, his intelligence isn't up to scratch. Even though he looks handsome at first glance, he cannot get a girlfriend because he often unintentionally ends up looking like a fool. Imai possesses impressive strength, usually throwing his opponents. However, he still couldn't win against many of the main antagonists. Mitsuhashi often tries to hinder Imai, especially when good things happen to him. Itou, on the other hand, usually gets along with Imai, respecting his honest efforts. He is one of the characters in this manga with the most character development, often looking for ways to better himself.

Yasuo Tanigawa (谷川 安夫, Tanigawa Yasuo)

Voiced by: Kazuki Yao

Imai's lackey and best friend. He respects Imai wholeheartedly and made a promise to follow Imai his entire life. He tends to get involved in a lot of troubles with Imai, and because of his small size, he's usually the first to get picked on. Despite his lack of strength, he has a lot of spirit, which sometimes intimidates people.

Tarō Koyama (小山 太郎, Koyama Tarō)

Voiced by: Wataru Takagi

An obese giant (197cm tall), who also decided to follow Imai as his lackey, after he was defeated in a fight. It is implied that he has anger issues and was thus expelled from his old school. His size makes him a formidable fighter even Imai acknowledges. He likes to refer to Imai as "aniki".

Makoto Nakano (中野 誠, Nakano Makoto)

Voiced by: Nobuyuki Hiyama

Originally from Ibaraki, Nakano transferred to Beni high due to his quarrel with the local yakuza boss' son. Despite his short stature, he was able to fight on par with Itou and Mitsuhashi during their school trip to Kyoto. His original goal in going to Chiba was to defeat Mitsuhashi, although he later settles in and even joins them in their raid of Akehisa.

Satoshi Katakiri (片桐智司, Katakiri Satoshi)

Being the banchou of the delinquent high school Akehisa, he is feared among his enemies and respected amongst his fellowship. He is on par with Mitsuhashi strength-wise, but stopped with his delinquent career the moment he stepped out of his school and entered society.

Takeshi Sagara (相良猛, Sagara Takeshi)

The main recurring villain of this manga, and as dangerous as a rabid dog. His methods are as dirty as Mitsuhashi's, however his own twisted character makes him always go a step further than Mitsuhashi. He is the only villain in this manga who managed to completely disable Mitsuhashi's abilities during their last encounter by severely injuring him.

Suenaga (末永, Suenaga)

Satoshi's successors as head (banchou) of Akehisa, he lacks his predecessor strength and characters, often using Akehisa sheer number and name to avoid actual fighting.

Ryōko Morigawa (森川涼子, Morigawa Ryōko)

A beautiful girl who usually fights with a shinai. When she is introduced into the story, she notices her cousin Satoru's bruises from Hokunei. Satoru lies and tells her that it was Mitsuhashi who did it, in order to keep her out of it. However, that only makes things worse and she tries going after Mitsuhashi and the others. Later on, she develops a crush on Imai due to his good nature. She was herself a (unwilling) delinquent and decided to change herself to a normal girl when she transferred, although it didn't last very long and she soon became respected by the other delinquents of her new school.
