'Brute' is the energy stored inside each individual. Living things can rarely tap into its infinite power. It's best to think of it as a cycle that follows a repeating wave over a straight line. The straight line represents our world, and the highest points of each crest represent a period in which brute activity surges, a most ripe period when people can develop wondrous supernatural abilities after reaching intense emotional states.

We follow Gyu, a 20-something-year-old man who fights those who use their gifts for evil. However, Gyu has a secret he needs to keep from his peers, he's been slowly losing his powers!
