I May Be a Guild Receptionist, but I’ll Solo Any Boss to Clock Out on Time, Vol. 2 (manga)

Your eyes don't deceive you, Alina! That's Guildmaster Glen Garia waiting at your reception desk in the Iffole Counter. And yes, of course he knows-that's his skill, after all. So listen to your boss and meet the elite Silver Sword party at the guild headquarters. All you'll have to do for him to overlook your moonlighting is to win a few little bouts... Is not only her day-job, but her life at risk as well? Or can the strongest skill blow away the details of an employment contract too?
