With Tami and Yaya having joined, the club finally has four members, and they begin working towards their goal of performing in the Hanairo Yosakoi Festival in the summer. But Naru and the others have never seen real yosakoi, so by Tami's suggestion, they go to the Shounan Yosakoi Festival.

Eu acho que é daí que o yosakoi vem!
