Summary:

Eris, the princess's personal guard, is extremely frustrated. The Queen keeps sending out these morons to save her best friend, aka the princess and future of the kingdom who got kidnapped by a dragon, and they keep coming back empty-handed.

She doesn't know why they keep coming back without her. She doesn't care, either. All she knows is that she will get her best friend back as soon as possible, with or without the Queen's permission.

Eris goes on this journey with the princess's brother, Ayako, as they try not to be too stupid with their decision-making skills and rescue the princess.
