On the moon, Runa herself appears as a five-year-old child in front of her long-lost twin brother and the doctor. After absorbing all of the flickers back into her body, Runa takes on her true form as a seventeen-year old teenager. The doctor intends to kill Runa once and for all by using the mysterious Applicon Buster that helped give birth to Kyosuke and Runa to begin with. Runa, however, spreads the Applicon Buster into the atmosphere towards Earth, much to Kyosuke's shock. The doctor is destroyed by Kyosuke reluctantly taking the soul and spirit of his adoptive mother, Mio, as the two were connected by sharing the same spirit and soul. Having been freed, Runa runs to Kyosuke and lovingly hugs him, happy to be reunited with her twin brother at last. But Kyosuke is worried about the new and improved Beta Applicon Buster being unleashed upon Earth and asks Runa why she would do such a thing. Nearby, Shiro wonders what choice Kyosuke will ultimately make: Will he save Runa or will he kill his own twin sister to spare all humanity?
