Youko is the female lead of the series. She has two main abilities. The first is jaen where she shoots a coiling strand of fire out of her fingertips. There is also dai-jaen which is just a larger, more powerful variation. The second ability is shukichi, an ability which allows her to teleport objects. Strangely enough, although she is generally fearless in the face of evil spirits, she is terrified of normal dogs. During an escape from Hake, she met the child Keita, who was with her for three days and shared his chocolate cake with her, which became one of her favorite things. Due to this incident, she wanted to become Keita's inukami to make a contract with him. Youko has feelings for Keita and she gets angry whenever he flirts with other girls.
