Genesin

A science fantasy battleshonen story with an arrogant protagonist full of pride.

In this story, 1 year later after the apocalypse, society began to recover with the half-built walls proof the apocalypse exists, the P.R.A.N.A. generator that caused all of the apocalypse(people turning into hatefilled murderous psychos, people transforming into abominations, and ghost-like entities manifesting randomly) was finally fixed and the society return to normal once again. The P.R.A.N.A.(or Psychogenic Reactive Adaptive Neural Acceleration) generator was created by the Philippine government(using the flood control budget) meant to make soldiers able to enhance their physical performance, able to withstand more damage, use their willpower as projectile, become what they desired to be, or even create anything with their mind, as to compensate the Earth's technology inferior to the incoming aliens

The protagonist was the last hate-filled psychos to be returned as a normal human being -- only a wrist-band device that maintains his normal state. Because of his situation, he earned derision from people around him. Allies felt more like enemies. But his arrogant demeanor keeps him from being discourage with their antics.
