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ソロ討伐しようと思います

Alina Clover has worked three years at the counter of the Iffole adventurers' guild, where her greatest enemy is overtime. What almost no one knows is that she carries a divine-tier Dia skill strong enough to shatter relics bare-handed. When dungeon bosses threaten to drag her workday past closing time, she dons a cloak, becomes the Executioner, and deals with the problem herself — then returns to her desk before guild master Glen notices.
