Legend of the Millennium Dragon

When middle schooler Jun Tendou is chased by a strange creature into a temple, the head priest, Genun, shocks him by revealing unsettling details about the oni demon he just escaped. Before Jun can process this, Genun abruptly transports them both back to the Heian period, where Heian-kyo-the ancient city that would one day become Kyoto-is under constant attack by the same oni. The nobles of Heian-kyo believe Jun is their destined savior, as he’s descended from a bloodline capable of controlling the dragon Orochi and wielding its immense power against the oni. But Jun is reluctant to embrace violence-and as he learns more, he realizes the oni aren’t what they seem.
