Susukihotaru is a shy half-spirit girl who looks like a normal girl with fox ears atop her head. She is chosen to be a spirit representative in the Ministry of Spirit Affairs and is partnered with Yoshinokazura Riken. Initially, she wants to be partnered with someone else, as she thought Yoshinokazura is big and scary. Upon hearing this, he crouches down and asks her if he is still scary. After this, their relationship greatly improves.
