Tokyo Ghoul is a manga set in an alternate reality where ghouls, monstrous (or demonic)
creatures that 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 various
superhuman abilities,
such as increased strength and
regenerative abilities; an ordinary
ghoul produces 4-7 times more kinetic energy in their muscles than an ordinary person; they also have several times more RC cells, cells that flow like blood and can instantly
solidify.
