The Weeping Ballet Shoes (Japanese: すすり泣くバレエシューズ,Susurinaku Bareeshūzu) is the 35th episode of the Yo-kai Watch Shadowside anime. It was broadcasted in Japan on December 14, 2018.
There is a post about “Weeping Ballet Shoes” on Usuranura. It seems that when wearing these ballet shoes, your body will start dancing on its own, and you’re unable to stop. What’s more, the shoes start getting wet, and you hear someone weeping. Suspecting that it’s because of a Yo-kai, Summer and the others start investigating right away. They question the original poster, who tells them that they received the shoes from a woman they didn’t know, and how they started dancing on their own as soon as they put them on. And supposedly, they ended up jumping out onto the road while dancing, but managed to take the shoes off at the last second, which had gotten strangely wet. The detective team return to the office to discuss things. And then Ikarin appears, saying: “There’s some Yo-kai at the beach that keeps crying all the time, so please help”.
