Yu catches the attention of the school bully Koyuhei Sanada, with his “magic tricks.” Kyouhei seems to know that there is something more than meets the eye.
Episode 2: Awakening
A new girl joins Yu’s class. Her name is Eimu Yoake. She has blue hair and red eyes. She is the girl who saved Yu and Hime from Kyouhei’s attack at midnight a couple of days ago. Eimu doesn’t mention Yu’s power and just watches over him. Suddenly strange incidents begin to happen around Yu – the buttons of his school uniform pop off – the glass in the window panes crack. When the ground splits wide open in front of Yu, he realizes the reasons behind all the strange things that have been happening. Kyouhei has been targeting Yu again.
Episode 3: Atonement
Eimu tells Yu that his power is called ‘Ayakashi.’ Her only explanation is “Once you find out, there is no turning back.” Yu does his own research about this mysterious power but with no success. Here we meet another Ayakashi Master, Pam Verne Asakura with blond hair and in black clothes. Pam’s Ayakashi ’Tengu’ is aggressive and overpowers Eimu’s Ayakashi ‘Satori’, defeating her and capturing Yu.
Episode 4: Ayakashi Master
Yu starts training to master his Ayakashi. Eimu refuses to help him as she is against Yu’s attempt. Yu keeps at it though Eimu tells him it is useless. One day, Yu meets a girl called Orie Natsuhara.

More Ayakashi masters start approaching Yu.

Yu learns that an Ayakashi Master called “HE” is targeting him. Yu and Eimu try to get more information from “HE”’s henchman Shougo Kadoya who is the Aykashi Master of “Shoukera – the Shadow Ayakashi.” When Shougo tells Yu that Eimu also belongs to “HE”’s mob, Yu becomes confused. All of a sudden, they are attacked by other Ayakashis and Yu is knocked unconscious. When Yu wakes up, he is sitting in front of a stranger in a wheel chair. In fact this is “HE” the leader of all the other Ayakashis.
Episode 6: Izumi
Through the Ayakashi power of hindsight, Yu recalls his tragedy from two years ago. In order to rescue Yu from the power of the Dragon which is embedded in Yu’s body, Izumi, Yu’s childhood friend, is working as a member of “HE’s” mob. “HE” orders Izumi to find the master of Dragon Ayakashi as he wants the power of Dragon, the strongest power of all the Ayakashi monsters. Although Izumi tries her best to hide Yu, “HE” eventually finds Yu. Izumi runs to warn Yu and “Akuro-oh; the Blue Devil Ayakashi” manipulated by Eimu, follows.
Episode 7: Isolation
Now that Yu knows what happened to Izumi he continues to use his power of hindsight to search for “HE” but finds nothing. Eimu tries to convince him not to engage in Ayakashi battles. But, there is no way Yu can take advice from the one who killed his girlfriend. Yu points at Eimu with his Dragon arm. In the mean time, “HE” summons a new Ayakashi Master. His name is Masayoshi Hori. Hori has been sentenced to death for mass murder.
Episode 8: Eimu
Controlled by Hori’s Manipulator Ayakashi, Eimu’s two Ayakashi monsters “Akuro-oh” and “Satori” attack Yu and Pam. Hori asks Yu to surrender and support him against “HE.” Hori knows “HE”’s ultimate ambition and in order to defeat the evil incarnation, Hori needs the power of Dragon as well. To convince Yu, Hori reveals the secret that Eimu has been keeping. Hori tells Yu that upon her death, Izumi asked Eimu to protect Yu. Eimu now carries the essence of Izumi within her.

Finally “HE” begins to make his move. A dense fog covers the entire city and isolates it from the outer world. Deidarabocchi, the Giant Ayakashi wonders around aimlessly destroying everything in its path. Hime Yakushiji, Yu’s classmate, is one of the fatalities. Yu and his allies prepare to defend their city and confront Deidarabocchi.
Episode 10: Together
“HE” is no longer a weak cripple. “HE” is now transformed into his true identity, “Orochi; the Serpent Ayakashi.” Although Yu’s Dragon is strong enough to destroy Deidarabocchi, “Orochi’s” power is even more forceful and seriously injures Yu’s Dragon. While Pam and Orie are attacking “HE”, Eimu rescues Yu. However the Dragon has suffered tremendous damage and has lost consciousness. Without Ayakashi’s regenerating ability, Yu’s life is in danger. Using the power of her “Satori Ayakashi”, Eimu enters Yu’s consciousness in a desperate attempt to awaken the Dragon.

The last monster, “Kebatake; the Misery Ayakashi” of Akio Maekawa detains Yu from going after “HE.” Although Yu’s dragon is still unconscious, Yu doesn’t hesitate to stand against Akio.
