Hunter Academy's Invincible Martial God

Synopsis:

The peaceful days of humanity came to an end when monsters poured through a portal in the sky, plunging the world into chaos. Just when all seemed lost, individuals with extraordinary powers—known as “Attributes”—emerged and became humanity’s last line of defense. They called themselves Hunters. To fight back, elite academies were founded to train the next generation of Hunters. Yusung Shin may have a low-tier attribute, but he’s set his sights on the top of Gaon Academy—the most prestigious Hunter school in the world—and he won’t back down until he gets there.
