Chihaya Aine: The band and the like are a nuisance. There are so many worlds waiting for me to save. Transform!

Fernina: I am no longer powerless. I can save everything in Fontaine! Including my half body! Transform!

Mei Raiden: The power of this body is not destruction, but hope. I will dispel the darkness and awaken the light! Transform!

Black Rabbit: I will never again shrink back and hide behind everyone. I will use the power of love and hope to defeat the darkness that overturns the little garden! Transform!

Qingque: I had to work before I changed my body. Now I have to work? That would be a waste! I just want to go out and play today. Even the Star God can't stop me! Transform!

Qingque: No, how come this transformed one is weaker than my original form?
