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?
If I can leave Nanase Karin behind 
and start over as a new person...
...إن استطعت التخلي عن ناناسي كارين والبدء كشخص جديد
Wenn ich Nanase Karin ablege und
ein neues Leben als neuer Mensch anfange …
Si dejo a Karin Nanase atrás
y vuelvo a empezar como otra persona…
Si dejo a Karin Nanase atrás
y vuelvo a empezar como otra persona…
Si je me débarrasse de Karin
et recommence sous une autre identité…
Potrei smettere di essere Karin Nanase
Se eu puder deixar Karin Nanase para trás
e recomeçar como uma nova pessoa...
Если отбросить личность Карин
и начать всё с чистого листа…
