S1·E3 Children of a Lesser God

The countess asks the children to stay only for dinner, assuring them they are free to leave afterward. During the meal, they learn that the three figures from the abandoned house are known as the "Gilgamesh." The countess wants Kiyoko and Tatsuya to help her fight them; however, neither wants to be exploited by her or the Gilgamesh, so they attempt to flee when the latter break into the countess's mansion. Ultimately, the situation resolves with the debt collectors reappearing at the door and the wealthy lady taking over the siblings' debts—on the condition that they help her.
