Earth had been invaded by creatures from another dimension, and it has been a few years since peace was restored, thanks to the help of various supernatural humans that revealed themselves during this invasion. Gwangik Yu, our protagonist, was born between two supernatural parents. His father is an immortal while his mother is a transformer with exceptional physical abilities along with the power to transform into beasts. Neither parent, however, is aware of each spouse’s power and both want Gwangik to follow in their footsteps.
