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

Alice stopped in her tracks at a safe distance and smiled at him. 


She licked his blood off the blades of her claws with pleasure. 


Elijah took the time to observe her claws to pick up clues but saw nothing unusual about them. 


“Were you hiding your true strength?” said Elijah. 


“No. Not at all. It’s my skill. I just get stronger the more damage I take.” 


Alice had the skill [You die, I die]: Your baby refuses to die. In desperate times, your child lends you its tenacity. 


The more damage you take, the greater the attribute bonuses. 


The user receives a stat boost when health goes below 90% and can receive a maximum of 50% in stat bonuses when health reaches 10%. 


“So as long as you don’t hurt me, I won’t get stronger, but then I just wouldn’t die right? Hahaha!” Alice laughed. 


A skill that strengthens her the more injured she gets?
