I May Be a Guild Receptionist, but I'll Solo Any Boss to Clock Out on Time

ギルドの受付嬢ですが、残業は嫌なのでボスを単独討伐しようと思います

Alina Clover took a receptionist job at the adventurers' guild for the stability, not expecting that a party's failure to clear a dungeon boss would mean she's still at her desk hours after closing. Rather than keep waiting on adventurers who can't get the job done, Alina summons a hammer and heads out to finish the boss fight herself. This light novel won the Gold Prize at the 27th Dengeki Novel Prize.
