The series began as a fairly humorous and lighthearted satire of Japan's teenage delinquent-gang subculture told from the perspective of Matsushita Tadashi (who also narrates these early Karate Bu stories), a 2nd year student at Kangokou High and a constant target of Kangokou's numerous bullies who beat him up routinely after school. He is almost always accompanied by his best friend Saitou Takaki, who is also constantly harassed. As the pair grow increasingly tired of being victimized they decide to join the titular Karate Club, which is notorious throughout Osaka's youth gangs for training and producing the city's most hardened and toughest teenage thugs while maintaining the facade of a legit school sports club. But... more>> when they join the club, they find themselves picked on just as much if not worse by the club's current members. But as the story progresses they grow to be increasingly capable fighters.

As the series went on it gradually changed its tone to a more serious and violent martial arts manga, with the narrative shifting from the perspective of Matsushita to Takagi Yoshiyuki, the smart mouthed, tough-as-nails captain of the Kangokou Karate Club.

Along with the manga's change in attitude and central character, the various teenage fighters throughout the series grew increasingly stronger and even began to tap into superhuman ki abilities, putting Osu!! Karate Bu in the company of other similar epic Shōnen fighting manga such as Yu Yu Hakusho, Dragon Ball, and Fist of the North Star.

Osu!! Karate Bu was wildly popular in its native Japan, but is otherwise almost completely unknown in most other countries. It spawned a four episode OVA mini-series released over a period of two years from 1990-1992, a 1990 live action movie, and a 1994 Super Famicom fighting game. <<less

A reboot of the award winning series Zekkyou Gakkyuu, with a bunch of new stories.

It is the 16th year of the Meiji era. Five years have passed since Kenshin Himura stopped the uprising of Makoto Shishio. Though the flames of his budding revolution were extinguished, the scars left in its wake are still felt across Japan. Remnants of his group—though scattered—still exist. Some have found peace while others continue to fight.... more>>

After a remaining faction tried to revive the revolution, Shishio's old sword fell into the hands of Ashitarou Hasegawa, an orphan boy who has never known a home. The conflict also leaves both Aran Inoue, a 16-year-old half-Japanese, half-American boy, and a mercenary girl named Asahi Kubota with a hefty price to pay off, with nowhere else to go. But luckily for these individuals, the Kamiya dojo has always been a place to accept wanderers without prying into their pasts.

The three are keen to start fresh, so when two members of Asahi's former clan show up demanding her return, Asahi refuses and things start to get ugly. In the midst of the chaos, the clan members drop a package containing a picture of dojo proprieter Kaoru Kamiya's presumably deceased father and his location—Hakodate, Hokkaido. With only this information, the members of the Kamiya dojo embark on an adventure across the sea in the hopes of finding news about Kaoru's father and the reason he is being targeted.
