While he believes he is the one causing the murders, he eventually finds out about the plan of Onizuka and discovers that it is Onizuka is who is responsible for the murders. Onizuka has experimented on himself and altered his genes, making him a humanoid grasshopper. The telepathy of grasshoppers allowed him to communicate with Shin, resulting in his witnessing the murders through his dreams. The syndicate learns of Onizuka's plans and have him institutionalized. As if the syndicate were not enough, a CIA agent tracks down Shin and wants him eliminated, for he doesn't know the true threat he could pose. The repulsed Shin digs to find out all he can about the experiment he foolishly volunteered to be a part of.
