Saiyuki: v. 3 by Kazuya Minekura
In the midst of battle with Sanzo and his team, a cursed human by the name of Rikudo impales the human leader, as he tries to protect Goku; Sanzo was once a friend of their now vicious enemy. In the melee, Goku's Youkai power limiter, the device that keeps his Youkai madness from taking over his soul, shatters, sending Goku into a violent rampage that yields for neither friend nor foe. It may take divine intervention to bring the ancient warrior back to his senses.
