Кунуґі Ай

Ai Kunugi sought out Misaki Saiki's help some time after her sister had committed suicide following the accidental murder of her infant niece. The baby's death was blamed on the mother, but Ai knew it was her sister's boyfriend, a yakuza boss named Kago, who was the one responsible. However, after the incident, Ai soon found out that, like Misaki, she too had the ability to see and communicate with the dead.

A very brave girl, Ai often looks up to Misaki, hoping to be as strong as her. Misaki, on the other hand, would rather have the girl ignore the many deceased spirits that Ai often encounters. Ai is also a classmate of Mitsuru Fujiwara, the young boy who is stalking Misaki.
