Where to Watch Blue Exorcist Free & Legally

In a world where humans and demons coexist, the boundaries between reality and the supernatural are blurred. The ruler of Gehenna, Satan, is desperate to expand his dominion into Assiah, but his plans are foiled when he's unable to find a suitable host to possess. Instead, he dispatches his son, Rin Okumura, to infiltrate the human world and eventually become a vessel for the demon king's return.

Rin's life takes a dramatic turn when he's suddenly attacked by demons, revealing a shocking truth: he's the illegitimate son of Satan. As he struggles to come to terms with his demonic heritage, Rin decides to reject his father's evil ambitions and join the ranks of exorcists, a group dedicated to protecting humans from demonic threats. With the guidance of his brother Yukio, a skilled exorcist in his own right, Rin embarks on a perilous journey to master his newfound abilities and defend Assiah against the forces of darkness.
