Aya Tademaru (
Aya is a young girl with long hair. She wears a short-sleeved dress with a collar.
When first introduced Aya seemed to be shy and innocent to those around her. However, she is quickly revealed to be quite confident, loud-mouthed and bratty- especially to Shiki. Despite being described as obnoxious by others, Aya is kind and often tries to help those that need her abilities.
Aya sees Kabane and Shiki in a souvenir shop, but says nothing. Later, when the group faces Akio Tademaru and fight the kemono he created, Aya appears in front of Kohachi Inugami and Akira and tells the kemono to not attack them. As Inugami is poisoned, she takes him to a spring, where she guesses it has healing effects as she had seen kemono drinking from it and getting better. Dipping his hand into the spring, Inugami heals his poisoned arm. Aya then asks them for help and that she needs Akio alive as she needs something from him.
Returning to Kabane, Shiki and Akio, Aya confronts Akio wanting to know where he hid the cocoon she made. Realizing that way she can't leave him or kill him, Akio doesn't want to reveal it. Inugami then offers his service as detective and calls Mihai Florescu, who recalls Akio's previous investigation resulting in he often checking four locations, one of which is a spring with certain flowers around it. Shiki recalls those are his mothers favorite flowers and Aya realizes the cocoon she made must have started to dissolve in the water, which results in the spring healing powers. They get to the spring and Shiki goes in it. As he emerges, he confirms that he found a cocoon with his mother in it. Aya is glad she found her and reveals she is the Golden Thread.
