Cellular Micromanagement Master

In this world teeming with psychic powers and mutations, Guts, an ordinary human, is transformed into a monster during a typical crisis. He gains the ability to freely manipulate himself and uses this power to enhance his physical body, joining an organization of human ability users.

He could freely control the actions of every cell, arbitrarily change the form of cells, manipulate cells outside the body, and transform and control other people's cells. This control ignored spatial limitations, transcended time, and everything transformed by him became himself…

To maximize his chances of survival, he planned to assimilate and integrate all life on Earth, but before that...
