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?
She didn't want anyone to 
think it was an astral body,
،لم ترد أن يظنّ أحد أنّه طيف
Sie wollte nicht, dass man
sie für eine Erscheinung hielt.
Pour éviter le doppelgänger,
E per evitare che fosse considerata 
la personificazione
Ela não queria que pensassem
que é só um espírito,
Чтобы её не приняли
за астральное тело,
