Summary[]
Kasumi is devastated over what happened and attempts to recover her lost voice, while the rest of Poppin'Party agree to practice without her until she recovers. She admits to Yuri and Asuka that she's losing her voice because she feels stressed and has been overdoing her practice, since she knows she's the weakest and least experienced band member. The other members of the band help her to overcome her issues, and to regain her voice.
