TEENAGE MUTANT NINJA TURTLES #16

It's Ujigami vs. Casey Jones, with Raphael caught in the middle! The Ujigami has vowed to protect the Turtles from their greatest enemies, so why is he attacking Casey? Meanwhile, Shinigami goes behind Karai's back to make a power play of her own, involving a dangerous new ally. The first step in their plan requires blood from a very specific target... and in very large amounts!
