Extinct Device Girl: Amazing Twins

Welcome to Our Dream! (1x2)

:

Upon having her ISH abilities analysed, Amane is warned that if she and Lilianne were to keep fusing, Lilianne would disappear. Later, Amane and Lilianne encounter Aya and attempt to get her to change her ways, with no luck. The next day, Aya appears again and attacks Amane with an illusionary monster during a show. With Amane powers alone not enough to win against Aya, Lilianne suggests they should fuse, assuring Amane she will undo the fusion before she disappears.
