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?
But if she thought the same thing 
would happen in the future...
...لكن إن ظنّت أنّ نفس الشيء سيحدث في المستقبل
Aber wenn sie glaubte, dass dasselbe
noch einmal geschehen könnte …
Pero si pensara
que pasaría lo mismo en el futuro…
Pero si pensara
que iba a pasar lo mismo en el futuro…
Mais admettons qu’elle ait craint
que ça se reproduise…
ma se poi avesse pensato che la stessa cosa
poteva ripetersi anche in futuro...
Mas se ela achou que a mesma
coisa aconteceria no futuro...
Но подумала, что вдруг
снова произойдёт нечто подобное?
