Shigan

Shigan is a fictional close-quarters combat technique from the One Piece manga and anime series. The term is commonly translated as finger gun or finger bullet, reflecting the method where the user delivers a rapid, pointed strike with a finger or set of fingers, mimicking the release of a small projectile.

In the series, Shigan is performed at very short range, with the attacker thrusting a finger or fingers toward an opponent’s body—often the torso or joints—at high speed. The emphasis is on precision, speed, and surprise rather than size or distance. Some depictions show the technique as simply a fast, piercing strike, while others imply that its effectiveness can be enhanced by the user’s physical strength and reflexes. In several scenes, Shigan is portrayed as being more lethal when supplemented by Busoshoku Haki (armament haki), which can increase penetration and impact.

Shigan is portrayed as a basic or specialized tool in the combat repertoire of various characters within the One Piece universe. Its use and effectiveness can vary by wielder, with some opting for multiple-finger variants or different hand positions to adapt to different opponents and situations. Like many fictional techniques, Shigan is defined by its signature style and dramatic presentation rather than by a fixed real-world martial-arts parallel.

Outside of One Piece, the term has become a recognizable trope in anime and manga to signify a fast, precise finger-based strike. There is no real-world martial-arts technique officially named Shigan.
