Kengo Hanazawa is a Japanese manga artist born in 1974, acclaimed for his darkly realistic and psychologically intense narratives. His breakthrough work I Am a Hero (2009-2017) revolutionized zombie manga with its neurotic protagonist and meticulously detailed artwork, earning international recognition and a live-action adaptation. Hanazawa's style combines hyper-realistic backgrounds with expressive character work, creating unsettling atmospheric tension. His stories explore social anxiety, isolation, and human fragility with raw honesty. Other notable works include Ressentiment and Boys on the Run, demonstrating his mastery of depicting ordinary people confronting extraordinary circumstances through claustrophobic, cinema-inspired visual storytelling.
