Shunsuke Saruwatari once stood as the undisputed ace of the notorious assassination firm 'Murder Inc.', yet the monotony of routine contracts left him deeply unsatisfied. Craving the adrenaline of clashing with a truly formidable rival, he walked away from the organization and carved out his own legend under the alias 'Submarine Ninja' across the streets of Kitakyushu. His signature technique combines baseball pitching mechanics with deadly shuriken and kunai throws, delivering both speed and lethal precision. Driven by rumors of the legendary 'Niwaka Samurai' lurking in Hakata, this blunt and guileless warrior sets out on a new path—only to unexpectedly reunite with his old high school friend Nitta, forging an unlikely assassin duo.
