She first appeared in Episode 21 when Sakata Gintoki of the Yorozuya wanted to buy an electric fan from her. However she thinks Gintoki wants counterfeit-gold machine: senpuuki (銭封機). This machine's name is pronounced the same way as electric fan (扇風機), causing much confusion for Gintoki, who was looking for such an electric fan. When Gintoki first entered her store and asked about a senpuuki, she mistaked it as an inquiry about her father's machine, and Gintoki for a member of the evil organization. However, after a series of events, Gintoki ultimately helped her destroy her father's machine so that it wouldn't be of any use to the evil organization. In return she offers an air condition but Gintoki wants an electric fan from her shop. During the Benizakura Chapter, she was one of the sources of information that Gintoki sought while investigating the purportedly missing sword. She would exchange Gintoki's jammed VCR for the cursed Blu-ray player. The cursed blu-ray player has a Blu-wraith inside the disc. Later Gintoki would exchange the Blu-Wraith's Kotatsu for the Cursed Kotatsu. (Source: Gintama Wiki)
