Immortal Core

Cores. Spherical growths of unknown origin that manifest in a select few giving them reality-bending power. Jin was born, raised, and given an artificial core for one single purpose – to serve as a sentient bioweapon for the Kudojin-kai family. Tired and discontented with his life, he tries to sever all ties with the family that enslaved him. But some ties are stronger than others.
