Kataoka Jinsei & Kondou Kazuma are a Japanese manga artist duo comprising writer Kataoka Jinsei and illustrator Kondou Kazuma. Working collaboratively since the early 2000s, they're best known for Deadman Wonderland (2007-2013), a dark action-horror series set in a twisted prison theme park that gained international popularity and an anime adaptation. Their partnership combines Kataoka's intense, plot-driven narratives with Kondou's dynamic, visceral artwork featuring explosive action sequences and grotesque imagery. The duo excels at creating dystopian settings filled with psychological tension and brutal violence. Their subsequent works include Smokin' Parade, continuing their signature style of dark fantasy with elaborate world-building. This collaborative approach allows them to produce consistently detailed, fast-paced manga that balances graphic action with complex character development.
