Tsukimi and Kuranosuke find various retro crockery for their flea market. Meanwhile, Shū's father has Hanamori ask his private investigator friend, Sugimoto, to tail Shū in order to find out about Inari. At the flea market, Kuranosuke discovers that a jellyfish shaped teru teru bozu that Tsukimi made sells well, so he arranges for the Amars to help her make more. Sugimoto learns that Inari is blackmailing Shū in order to seal the development deal.
After seeing Tsukimi entranced by frilly material, Kuranosuke wonders if he is having feelings for her. Meanwhile, Hanamori accidentally informs Shū about Sugimoto tailing him. Assuming Tsukimi might be interested in clothes, Kuranosuke suggests they work together to make jellyfish dresses to sell.
