"Now that you mention it..." Pitch forms a toy horse out of the shadows in his hands. "This is a tool used to conjure and control shadow creatures. Though it isn't powerful, you can create shadow followers to do your bidding."

Pitch hands the toy to Roichi. "Use it to keep an eye on those kids. Use it to go to the caves without being there, you'll be able to see through the eyes of your creations... Just don't use it to snoop around the faculty staff. They don't like being spied on, and if your caught with this, I'll deny everything. So don't mess it up."

Pitch put on a surgical mask and closed a curtain around one of the student patients. He proceeds to cut the student open, looking into his insides. "You might not want to see this, I'm not sure you have the stomach for it." 

The students organs were black, and so was his blood. The heart wasn't beating, but the kids face looked alive. He was lucky he was on sedatives, the student was asleep and couldn't feel a thing.
