Action Is Required

 Luke who had Shadow girl squirming in the grasp of his intangible chaos energy, began to probe into the transparent black ball at the place her heart was supposed to be in the body- her shadow core.

 It was a common situation for every energy being to own a core that could stop the entire form from falling apart. Probing this core with a foreign energy causes immense mental pain to the energy involved as their form is dragged and panned out.

 It felt like someone with a deep flesh wound, spread it out and allowed a gale to blow into it. It was like thousands of needles being scrapped against the edges of a fresh bruise.

 "Is this all you've got? I can- ahhh! Do this all day!" Shadow girl screamed as she fervently began to twist and turn, trying in vain to break out of the indescribable torture.
