Manga about teenage delinquents, their gangs, fights and codes of loyalty.
4Reduced, this term gives 4. It sits on The Structure with the rest of a structure.
What it means
Delinquent manga, known in Japan as yankī or furyō manga, are about rebellious teenagers: high-school gangs, motorcycle crews, fights between schools, and the codes of loyalty and honour that hold them together.
What it looks like
Characters wear modified school uniforms and pompadours, ride loud motorcycles and fight to protect their friends or their school's reputation. Despite the violence, the stories are often about friendship, belonging and growing up, and the heroes are usually decent people.
Notable examples
The genre flourished in the 1980s and 1990s. Tōru Fujisawa's Shonan Junai Gumi and its sequel Great Teacher Onizuka, in which a former gang leader becomes a teacher, are among the best known. More recent series, such as Tokyo Revengers, have brought it to new readers.
Why it matters
The genre reflects a real youth subculture, and has shaped how manga portrays rebellion: as a phase of loyalty and defiance that a hero can grow through into adult responsibility.
The term by its numbers
Set against the Pythagorean table, the term totals 67. Reduced, that is 4. The weight sits in “Delinquent”, which carries 49 on its own and reduces to 4.
The reference files it as a structure. The number's contribution is structure, labour, and the building of lasting systems — and with it the 4's insistence that what lasts must be built patiently, which is the thread the reference follows here.
Beneath the 4 sit two smaller figures: 6 in the vowels, 7 in the consonants. Responsibility underneath, inquiry on the surface. The gap between them is where the subject is most interesting.
Read on the 4's terms, this entry asks you to look for the constraint the subject was working inside. The 4 confuses the frame for the work. Structures outlive their usefulness, and several entries here describe conventions kept long past their reason. The other entries that reduce to 4 are collected on The Structure.
