Guild no Uketsukejou Desu ga, Zangyou wa Iya Nanode Boss wo Solo Toubatsu Shiyou to Omoimasu

Alina Clover assumed a desk job in the public sector guaranteed safety and stability, which made her role as a receptionist for the Adventurers Guild seem like the perfect career. In practice, though, that dream unravels into an overtime nightmare every time adventurers get bogged down clearing a dungeon — and the mountain of unfinished paperwork comes crashing onto her desk. Determined to spare herself the endless overtime, Alina settles on the simplest solution within reach: going out to defeat the troublesome monsters herself. The catch is that a mysterious fighter who appears out of nowhere, dismantles a boss single-handedly, and vanishes without claiming any credit is bound to become the stuff of rumors. Complicating matters further, the job she treasures strictly forbids its staff from taking on side work, meaning her covert exploits could cost her everything she has worked for. And when the leader of the Silver Sword party draws dangerously close to the truth, trouble seems all but certain to follow.
