I May Be a Guild Receptionist, But I'll Solo Any Boss to Clock Out on Time, Vol. 5 (Manga) - Mato Kousaka

The long-awaited Centennial Festival is fast approaching! Alina is burning the candle at both ends to make sure she can fifinally take time off and enjoy the festivities, but uninvited chaos is adding fuel to the overtime fifire! Rumors about secret quests with Dia skill rewards have been enticing adventurers to take risky missions during the holiday season... Luckily, Silver Sword has their own reasons for wanting to pacify the crowds, and Alina is willing to go Executioner mode to help defeat rumormongers. They're quick to fifind and confront the party spreading the lie, but maybe that only means replacing one incendiary claim with another--because the enemy's tank accuses Lululee of being a murderer, and she can't seem to deny it?!
