᠌ ᠌Tokyo Ghoul is a manga set in an alternate reality where ghouls, monstrous (or demonic) creatures who look like normal people but can only survive by eating human meat and blood, live in secret among the human population and hide their true nature to avoid persecution by the authorities of the human world. Ghouls have different superhuman powers, such as increased strength and regenerative abilities; a normal ghoul produces 4-7 times more kinetic energy in their muscles than a normal human being; they also have a several times larger number of RC cells, cells that flow like blood and can solidify instantly.
