Experience the third installment of the provocative Biko series and step into the shoes of Takumi, an ordinary Japanese guy with a compulsion for tailing and observing pretty girls in full 3D environments. Master the art of stealth by walking, running, and crouching to remain undetected as you pursue one of two starkly different objectives: win a heroine’s love through genuine romance, or stalk her into non-consensual encounters—including rape. Tense cat-and-mouse gameplay, dynamic AI patrols, and hidden routes reward patience and cunning, keeping the thrill alive at every turn.

Meet five unforgettable heroines, each offering unique challenges and story branches: Rin, the dark-haired schoolgirl; Reiko, the compassionate redhead nurse; Chris, the agile blonde ninja; Mayu, the stylish uniformed waitress; and Mio, the serene shrine maiden. Every character reacts to your approach in real time, unlocking multiple endings that reflect your choices—whether heartfelt or morally twisted. Boasting rich visuals, evolving scenarios, and mature content, this stealth adventure dares you to explore every shadow and secret for a truly boundary-pushing experience.
