Now that the heroes have killed all of the monsters, they're ready to face the "ultimate boss" . They're at the end of their rope, and they can't even go any farther. The boss has appeared, and now it's the ultimate boss. It's not like the black dog killed the monster, but there's still nothing on the ground. The black dog is still alive, but he's cut off his arm. He's so upset that he wants to chop off his sister's arm.
