My Patients Are All SSS Fiends - Episode 3

A powerful being from the demon realm begrudgingly admits the skills of a human he paid, resolving to uncover his secrets as a cover for seeking further treatment. Elsewhere, on a perilous 'Death Train,' passengers are given a harsh introduction to the rules of survival: every action costs points, which must be earned through quests or by volunteering for dangerous supply runs at stations like the upcoming Land of Weeping Angels. Those who fail to accumulate points will be eliminated. As the discussion period begins, one passenger focuses on planning their next move within this deadly system.
