"Steel Lady Nanase"--the urban legend of a faceless, bloodthirsty phantom who had once been a voluptuous idol-- as gone from myth to terrifying reality thanks to Rikka's powers. In order to defeat this fictitious monster, Kotoko continues to present her "four solutions" to create a new "truth," as Kurô uses his abilities to defeat the spectre once and for all. With two solutions rejected and only two remaining, canKotoko's invented inference put the myth of the Steel Lady to rest once and for all, or is the fate of her and Kurô's futures completely out of her hands?
