Hell: The place where even Shinigami aren't allowed to go, if you go there you die. The denizen's of hell known as the "Togabito" have kidnapped Ichigo's sister Yuzu and attempted to take Karin as well. In an attempt to stop them, Ichigo and his friends are crushed by the Togabito's overwhelming power. A mysterious man named Kokutou (a Togabito himself) saves Karin but the Togabito succeeded in taking Yuzu to hell. In order to get her back, Ichigo and co. must enter Hell and battle the Togabito. A lot more than Ichigo's sister is at stake though, the Togabito's goal is to escape hell. To do so the seal between the worlds must be destroyed and when the seal dissolves, the worlds will connect and the human race will be destroyed. The Togabito named Shuren wishes to use Ichigo's perfect hollow form to break this seal, and is using Yuku as leverage. If Ichigo uses his Hollowfication he will lose control and never return. With Kokutou leading the way Ichigo, Rukia, Uryuu, and Renji march into hell to save the world.
