Arsela is a female dragon with two heads. Unable to fit in with the other dragons in her hometown, she chose to work far from them and took a job as a delivery courier on the frozen snowfields. Although she is relatively resistance to the cold compared to others of her kind, the harsh chill still seeps into her bones, and she struggles to keep up with conversations among her coworkers. As a result, she endures difficult and lonely days.
One day, Shoa arrived at the same workplace. Like Arsela, Shoa was a dragon from another region and felt out of place among the staff. Sensing that their circumstances were similar, Arsela began actively teaching Shoa the job. In the way, she became one of Shoa’s few friends. However, she cannot understand Shoa’s habit of spending time at home with her body taken apart, and to be honest, she finds it unsettling.
