Emperor of Demise Arrives! (It Was the Final Episode Before We Knew It) - S1.E13

Their day off is peaceful, and Miss Kobayashi spends her time relaxing with the others as usual. However, while out shopping, Tohru suddenly stops to think on the street--Miss Kobayashi is human, and what will she do when her lifespan runs out and she dies...? They can't be together forever. They'll have to part someday. She knew that. She was prepared for that. Yet still, Tohru's mind is in turmoil, and the final blow is dealt when the Emperor of Demise--her father--appears before her.
