Chronicles of the Demon Warden

Zeke Larson, a man who has transmigrated into this world from the modern age, carries a hidden advantage called the Demonbane System, which grants him mastery of brutal fighting techniques. He joins the Demon Wardens of Drosa as a raw recruit and climbs through the ranks from novice to captain and then major. Alongside his companions Tristan Clark and Luna Sawyer, he moves through a dangerous land full of lies and demonic menace, uncovering shadowy plots as he goes.
