Volume 9 is the ninth volume of the manga series, Blue Exorcist (青の祓魔師 Ao no Ekusoshisuto) by Kazue Katō. The front cover features Shura Kirigakure.


Fight hellfire with hellfire!

All of Rin's friends have done their best to hold off the deadly Impure King so Rin can confront it. Now it's entirely up to Rin to finish off the gigantic demon. Although Rin has finally drawn the Koma sword and found his confidence, that alone may not be enough to defeat the Impure King! And Yukio's battle with the possessed Saburota Todo may have awakened something dark deep within him.[3]

The Story so Far[]

Unknown to Rin Okumura, both human and demon blood runs in his veins. In an argument with his foster father, Father Fujimoto, Rin learns that Satan is his true father. Satan suddenly appears and tries to drag Rin down to Gehenna because Rin has inherited his power. Father Fujimoto fights to defend Rin, but dies in the process. Rin decides to become an Exorcist so he can someday defeat Satan and begins studying at the Exorcism Cram School under the instruction of his twin brother Yukio, who is already an Exorcist.

On day, they learn that someone has stolen the left eye of the Impure King from the academy's Deep Keep.

Rin and the others go to the Kyoto Field Office of the Knights of the True Cross to assist in the defense of the Right Eye of the Impure King. When they arrive, they learn that almost half of the combatants there belong to a religious sect named Myo-o Dharani and their leader is Ryuji's father, High Priest Tatsuma Suguro.

Todo, a former Exorcist, stole the Left Eye and then tricked Mamushi, who belongs to the Hojo family of Myodha archpriests, into giving him the Right Eye. Todo then uses the eyes to awaken the Impure King and seize the power of Tatsuma's familiar, Karura.

Meanwhile, Rin uses his forbidden flame, causing the Order to imprison him. After his friends break him out, they all prepare to face the Impure King, who has finally revealed its true form. Ryuji receives the power to erect a barrier from his father Tatsuma, but there's very litte time. Rin finally draws the Koma Sword and confronts and Impure King!![2]

In the next volume…[]

The Impure King was defeated in Kyoto, but halfway around the world, another powerful demon rises that may have some connection to events in Japan. As the Vatican scrambles to respond, the enigmatic Mephisto Pheles continues to plot and scheme. Meanwhile, Rin tries to make friends outside the Exorcist cram school, though escaping his infernal birthright may be forever out of reach.


The long Kyoto/Impure King arc ends this volume! I feel like self-study just might have paid off in slightly better pseudo-Kyoto dialect!

On to volume 9!
