Kotoko came up with three solutions, but they all got shot down. Kuro keeps trying to grasp the future where they can defeat Steel Lady Nanase, but Rikka made it disappear once again. But Kotoko wasn’t done yet. Steel Lady Nanase is not a ghost. What is Kotoko’s 4th solution that may finally put an end to Steel Lady Nanase’s existence once and for all?
So to make Nanase Karin completely 
dead in people's minds,
،لتجعل ناناسي كارين تموت نهائيًّا في أذهان الناس
Um Nanase Karin in den Köpfen
der Leute wirklich für tot zu erklären,
Entonces creó a la Dama de Acero
Nanase para asegurarse
Creó a la Dama de Acero
Nanase para asegurarse
Pour pouvoir disparaître
pour de bon,
avrebbe inventato Nanase d'Acciaio
per far morire definitivamente Karin Nanase!
Então, para matar completamente a
Karin Nanase na mente das pessoas,
И чтобы это предотвратить, она создала
из ничего призрачную Стальную деву!
