Known as "Proprietário" or "Casero," this humanoid character features blue skin, purple hair, and a head shaped like a daikon radish, consistently dressed in blue clothing. He serves as the landlord for Milk and her companions, whose residence remains perpetually six months behind on rent. Regularly attempting to collect the overdue payments, he approaches Milk's home only to face consistent evasion through her insults, deceptive tactics, or Tetsuko's incapacitating gas. Each encounter concludes with him retreating across a ladder to his adjacent home after being shocked, tricked, or repelled. His personality displays observable anxiety, exemplified by distress over misplacing his "purse" before quickly locating it. His sexual orientation is explicitly stated in the Japanese version of Episode 9, "Financial Decay Peninsula," and openly referenced in other episodes, confirming his identity as a gay character. His background, narrative function, and interpersonal dynamics remain consistent across all documented media, with his role focused solely on the recurring rent conflict and comedic interactions from failed collection attempts.
