The Invincible Full-Moon System

Humanity's supposed sins ushered in a great calamity, but it was the Supernatural Emergence that truly tested them. Supernatural creatures materialized, forcibly claiming half the Earth and massacring humans encountered. These overwhelmingly powerful beings quickly conquered dozens of countries, pushing humanity to the brink. However, a turning point arrived as humanity began to awaken magical powers, gifted by the gods. These individuals, known as the Awakened, became humanity's bulwark. Rex Silverstar, a normal boy, endured a traumatic experience during the Emergence when a werewolf destroyed his family and home, leaving him alone and fueled by deep hatred for supernatural beings. Determined to eradicate them, he joined the military as a teen, only to discover he needed to be an Awakened to defeat the werewolf that orphaned him. On a night of near-death, on the verge of losing his soul, Rex was offered a chance by the full moon. A system promised him the power to match the supernaturals. His elation turned to shock upon viewing his stats, revealing a disturbing truth and a looming transformation. The system warned of a low sanity stat, an impending Blood Moon blessing, and a forceful transformation he wasn't prepared for. Overwhelmed by bloodlust, Rex found himself questioning his identity and the terrifying changes beginning to take hold.
