Solo Leveling, Volume 12 of 15 (by Chugong)

Jinwoo faces off against the Monarchs in the heart of Seoul, but three otherworldly beings prove to be too much even for him. It’s the end of the road for this hunter―except that death means little to the Shadow Monarch, King of the Dead. As Jinwoo confronts the true source of his newfound powers at long last, a hunter who was thought to be lost forever steps in to protect the defenseless body of humanity’s last chance, no matter the cost!
