=== Setting ===
The world of Blue Exorcist consists of two dimensions, attached to each other as a mirror and its reflection. The first is the material world where humans live, Assiah (物質界(アッシャー), Asshā), and the other is Gehenna (虚無界(ゲヘナ), Gehena), the world of demons, which is ruled by Satan. Originally, a journey between the worlds, or even a contact between them, was impossible, however, any demon is able to pass to the dimension of Assiah through the possession of a living being in it. Even so, demons have historically wandered among humans unnoticed, visible only to people who have had contact with demons before.
In contrast, there are Exorcists, people who train to destroy demons who act in a damaging manner in Assiah. With more than two thousand years of existence, this group has several branches all over the world being secretly under the command of the Vatican itself and acting in a clandestine manner.

Plot

The story revolves around Rin Okumura, who, along with his younger twin Yukio Okumura, was raised by Father Shiro Fujimoto, an Exorcist. One day, Rin learns that he and Yukio are the sons of Satan. Witnessing Shiro dying to protect him, Rin draws the demon-slaying sword Kurikara (倶利伽羅), which restrains his demonic powers. From that moment on, Rin not only gains demonic features like fangs and a tail, but also the power to ignite into blue flames that destroy almost anything he touches.
Rin wishes to become an Exorcist like his guardian to become stronger and to defeat Satan. He enrolls at the prestigious True Cross Academy (正十字学園, Sei Jūji Gakuen), an exorcist cram school, which is actually the Japanese branch of the True Cross Order (正十字騎士團, Sei Jūji Kishidan), an international organization dedicated to protect Assiah from Gehenna. Much to his surprise, Rin finds that Yukio is already a veteran Exorcist and is one of his teachers. Thus begins Rin's journey to become an Exorcist, accompanied by his brother and his fellow students who quickly become his close friends.
