Miroku comes across a village in which he remembers meeting a young girl named Shima, who was ill two years past. He had lecherously proposed to her then, swindling her parents to buy his expensive medicinal herbs. She is being forced into a marriage with a catfish demon, despite the fact she claims to be betrothed to Miroku. It is revealed that her father unknowingly promised Shima to marry the catfish demon, due to using lake water for the medicine and regularly praying to the shrine by the lake. The whole situation causes Sango to begin to doubt Miroku's feelings for her. Shima later insists she had lost her virginity to Miroku when he first met her and Sango finds she cannot easily forgive him. The catfish kidnaps Shima and then Sango as his intended mistress, but Miroku uses his Wind Tunnel to dry up the lake and defeat the yōkai. Shima reveals that she lied about being betrothed to (and sleeping with) Miroku, only to avoid marrying the catfish demon in the first place. Sango and Miroku reconcile.
