The Sister Strikes - S1.E10

Satsuki inadvertently drinks a medicine that causes her to shrink down to a tiny size. Having to spend the day riding on Yuzu's shoulder, Satsuki is amazed by how good Yuzu has gotten at her job. After Satsuki returns to normal size, she and Yuzu attend to Hiiragi and her fellow priestess Ayame when they come to stay at the Konohanatei. As Satsuki deals with her sister's erratic behavior, Yuzu becomes worried over when Satsuki will inevitably leave the Konohanatei to be a priestess. At the behest of one of the guests, Satsuki is asked to perform a kagura dance alongside Hiiragi, leading her to feel frustrated when comparing herself to her. After Hiiragi takes her leave the next day, it is revealed she feels that Satsuki was chosen over her to work at the Konohanatei.
