That Which Resides in Hell (1x10)

Air date: Sep 09, 2011

Sion and Nezumi climb through the huge pile of bodies where they were dropped in and infiltrate the facility searching for Safu. Meanwhile, Rikiga and Inukashi leave the baby Sion saved to one of the dogs and gain entry into the facility by themselves to clear a path for Sion and Nezumi. Somehow, Sion knows exactly where to go and where all the cameras are, and this makes Nezumi a bit suspicious. He and Sion fight their way through the complex until Nezumi is wounded by a security guard. Sion kills him in retaliation much to Nezumi's grief. When the duo manage to get through Safu's location, they find that she broke herself free and the researchers around her are lying dead on the ground.
