Through the power of Ayakashi's "returning pillow", Yu remembered the tragedy that occurred two years ago. Yu's childhood friend Izumi Makihara worked for Yu to help Yu from the power of the "dragon" Ayakashi sleeping in Yu. However, "he" who wants to co-exist with Ayakashi also wants the power of the strongest Ayakashi "dragon" and orders Izumi to search for the user. Izumi tries to hide Yu from his eyes, but instead, Yu's existence is known. Izumi runs towards Yuu. Behind is the shadow of Aim who controls the "king of evil ways".
