Run! Ninja is a series of ninja parkour games composed of black, white, and gray tones. The terror and excitement hidden in the darkness erode the game's protagonist, Abby.

Mysterious creatures, whose origins are unknown, have corrupted all life. Abby can only flee aimlessly, trying her best to avoid being caught by the shadows and attempting to uncover the secrets of these creatures. Along the way, you'll encounter various magical beings that sometimes hinder your escape and sometimes help you evade pursuit.

Endless roads and realistic weather will immerse you in a true adventure world.
