The Red Kappa is a special kind of Kappa found in the land of Tono in northern Mutsu province. Although they also have the dish-like depression on their heads and a turtle-like shell on their backs like regular Kappa, their skin is actually reddish in colour. Additionally, they do not flee at the sight of humans, and have been known to attack children and women who wander near the rivers where they dwell. However, it is said that some of them have abandoned their evil ways after being captured. There is a location known as Kappabuchi in Tono where many Red Kappa can be found.
The shell on the Red Kappa's back is extremely hard, and nearly negates any attacks from behind. The dish-like depression on their head is almost always wet, and it is thought that the Red Kappa is weakened if it dries out. It is also said that they will die if the dish is cracked.
