An alien parasite inside a cat ambushes Hikaru. Unbeknownst to it, he's a psychopath who killed his mother and can reverse-hack the parasitic cells, taking its body and powers for himself. Evolving from absorbing other living organisms, he begins changing as he becomes sensitive to emotions. Ironically, an alien made him more human than ever. Dragged into an ever-growing war between parasites and humans, will Hikaru become the dark hero humanity needs? Or will he fulfill his dream of world domination?

At the same time, the Master System and its power are in peril as a result of Hikaru's actions. A simple nobody named Elijah reincarnates with the Hero System and is sent back in time to restore order to the universe.

Read between the Dark and light chapters of Parazyte, explore the Naruto and Sasuke type dynamic of the two characters, the vast world-building and in-depth character development with rich side characters (sprinkled with 2D characters for fun). 

Warning: Book recommended for 18+. Realistic violence and death is the theme. Hero chapters are sometimes light-hearted but often contain sad realities.

The world shakes under their overwhelming power. The fate of the world depends on who becomes a God. 

Readers from a parallel universe can affect the storyline with their quantum tremors.

OP Parazyte

'Our kingdom is in the middle of the continent. How strange is it that foreigners from another continent reached past all the other nations to here?' 


She thought that maybe this was classified information, so low-ranking people like her wouldn't know. 


"So… what's your name?" asked Elijah. 


It reminded Elijah of his ex-crush Stephanie who was Nicole's right-hand girl. Nicole had recently tried to blackmail him into dunking his face in toilet water and Alyssa into using her tampon as lipstick. 


This Stephanie didn't look like the other. The only matching details were their black hair and nice smooth skin, but this Stephanie was much taller and had more curves. It was just a coincidence. 


Elijah was curious about what she said about being a monk. 


Before he could ask, Stephanie asked him a question. 


Elijah eyed the top left of his status screen.
