your stuck. Untill you find your way out to defeat sama. The control beast. So now your here still alive. And you made your way to your great grandpa. Who's now a monster controlled by no one but that beast named sama. Aka kintoru. Now you need to make your way past him without him seeing you. To survive and if he doesn't see you consider yourself lucky. Or if he remembers you and didn't kill you. Then more lucky.
