Plot
Having been abducted by Zero and her suffering absorbed by Nanahoshi's miniature galaxy, Towa is forced to recall her troubled childhood memories in the modern era when she was constantly mocked by bullies for her "Making Setsuna up" although she wasn't lying. It is during this ordeal that Zero's motives are revealed. Meanwhile, Sesshōmaru goes to Kohaku to bring Setsuna to the Sacred Tree of Ages, where the hardhearted Half-Demon Princess comes face-to-face with her ailing mother for the first time since her Dream Butterfly was cut down and started the re-progression the silver-scale curse upon Rin's body quickly. A weakened Rin informs Setsuna that cutting the thread of fate will not lift the curse but that she must first save Zero from herself. Baffled, Setsuna reminds her mother that Zero is her enemy and that she does not deserve pity from her. Rin, however, assures her youngest twin daughter that the curse is Zero's way of being unable to let go of her regerts and bitterness. She gives Setsuna a glowing yellowish light, something that Setsuna recongizes. Setsuna exits the Sacred Tree of Ages and heads to where her twin sister is with a thread of fate as her guide.

Riku and Rion finally manage arrive to help Towa, only to see that the most optimistic and warmhearted of the Half-Demon Princesses has lost herself to her deepest fury and hatred, which has resulted in the awakening her innermost demonic self in full swing. However, this is exactly what Zero has been hoping for. Wanting to send Towa to Hell personally, she absorbs all seven of her Rainbow Pearls into her eyes, thus being granted even greater demonic abilities than ever before as a rainbow-colored demonic aura is emitted all around her, which shocks Riku.
