NINJA SLAYER NEO-SAITAMA IN FLAMES(ニンジャスレイヤー ネオサイタマ炎上)

About this game

Ninjas are known to be fast, and their attacks are even faster! Unleash intense, ultra-fast attacks to defeat any yakuza and ninja in your way!
Use Karate to dispatch the cannon-fodder small-fry without even needing to stop. Tougher enemies on your tail? Harness the Ninja Dash, a high velocity attack that lets you race through enemies and terrain with ease, and finish off your foes with Hissatsu Waza, special ninja techniques that boast terrifying power.



The Ninja Slayer story is set in Neo-Saitama, a futuristic fictional city. Race across skyscrapers, streets and more across eight unique stages on your quest to reach Tokorozawa Pillar, the ninjas’ final base, all against the backdrop of the night in a bright, bustling metropolis.



The original “Ninja Slayer” was a blockbuster hit that sold more than 4.44 million copies in novels and manga! The world, characters and setting of Ninja Slayer: Neo-Saitama in Flames was lovingly created based on the manga, with stylish graphics that feels like they popped right out of a manga page!
