The princess Nazuna was once the most powerful and talented swordsman in the kingdom, until an evil spirit possessed her, rendering her unable to lift her own sword. When Hibiki discovers that the so-called evil spirit is actually a flock of baby chicks that see Nazuna as their mother and constantly perch on her, they both attempt to find a way to remove them. Nazuna believes this is her punishment for something she did in the past. Later, she confides in Hibiki that she used to have a baby chick named Picco, which unfortunately died due to her negligence.
Despite trying to distance herself from everyone, Nazuna is very friendly and eventually becomes good friends with Hibiki. Together, they work on solving the issue with the baby chicks while also helping Nazuna come to terms with her past.
