Sierra, a high-spec girl, dreamed of a relaxed life working at a small guild in a small town, earning a moderate salary... but her new assignment was to the busiest city in the world?!
"Overtime is the worst! I want to go home early!" she declared, determined to eliminate waste! Efficiency is everything! Her super-fast processing of documents proved to be her undoing.

Her essential receptionist skills—"Appraisal," "Authenticity," and "Copy"—were quickly maxed out, and her exceptional competence, unusual for a 19-year-old, made her the center of attention among adventurers!

To make matters worse, she accidentally tamed a Cockatrice, a monster powerful enough to destroy an entire town, attracting the attention of the lord?!

The more troubles she has to deal with, the later she gets home?
