Yuzuka invites Chiya over to help test her magical abilities, and they find out some interesting things when they test Yuzuka's transformation.
Why don't you want people to see 
you in your swimsuit, Yuzuka?
Warum willst du nicht, dass Leute
dich im Bikini sehen, Yuzuka?
Pourquoi tu détestes tellement
qu’on te voie comme ça ?
Yuzuka, perché ti dà tanto fastidio
che ti vedano in costume da bagno?
Por que você não gosta de ser 
vista num traje de banho?
