Jutsu Hero is a free, browser-based rhythm game where you perform Naruto-style hand seals in front of your webcam. A real-time computer-vision model (MediaPipe Hands + a custom-trained ONNX classifier) recognizes each of the 12 zodiac hand seals and turns correct sequences into jutsus — Kage Bunshin no Jutsu, Chidori, Katon: Goukakyuu no Jutsu, and more. No download, no account, no backend required: it runs entirely in your browser.
