Akko approaches a typical public housing housewife on her way home. At first, Erika is cautious, but when Akko points out her skin condition during a street consultation, she gradually becomes interested, saying, "Maybe I should give the free diagnosis a try~." Drawn in by Akko's passionate pitch, Erika is eventually taken to the lab—all justified by Akko's claim that it's "for the sake of your hormonal balance!" The natural progression of events makes this episode particularly appealing.
