Tsubame is a versatile assassin-for-hire who hides a complex secret within his prosthetic limb. By activating a mysterious mechanical arm, he switches between four distinct personas, each possessing unique combat skills and lethal weaponry.

In this gritty sci-fi series, the protagonist navigates the underworld using a unique system to swap identities. While Tsubame favors rifles and martial arts, his other modes include the expert sniper Penguin, the dual-pistol wielder Suzume, and the heavy-artillery specialist Washi.

Each personality brings a different tactical advantage to the battlefield, ranging from silent long-range takedowns to chaotic gatling gun suppression. As Tsubame carries out his missions, he must uncover the truth behind his cybernetic arm and the personalities living inside him.

The assassin Tsubame uses a specialized mechanical arm to swap between four lethal personalities in the sci-fi manga 6 no Trigger.
