I May Be a Guild Receptionist, but I’ll Solo Any Boss to Clock Out on Time, Vol. 4 (manga)

Light from the guiding crystal shard means someone in Silver Sword is on the brink of death… And the one thing Alina values more than her safety and comfort is the lives of her friends! So she charges deep into the Chalk Tower, past Lowe and Lululee, to the boss room, where Jade lays in a pool of his own blood… Alina’s temper flares at the sight, but the Dark God Silha might be more than she bargained for—he too wields a Dia skill!
