Na Honjaman Level Up: Ragnarok

After witnessing the death of one of their own, the Absolute Ones — creators of the many universes outside of our own — frantically seek to fill the power void left by their fallen brother. With earth's existence in danger once more as gates spill monsters into our dimension, Seong Su-Ho must answer the call and conquer the shadow dungeon while learning of his father's legendary legacy.
