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?
Some percentage should've switched 
over to the side that doesn't believe
ينبغي أن تكون نسبة معينّة غيرت موقفها لعدم تصديق
Ein paar Prozent dürften nun auf der Seite sein,
die nicht an den Geist, die stählerne Dame Nanase, glaubt.
Al menos una parte debió
cambiar al lado que no cree
Al menos un porcentaje
habrá dejado de creer
Un certain pourcentage
a dû basculer du côté
Una certa percentuale dev'essere passata dalla parte di chi
Alguma porcentagem deve ter mudado
para o lado que não acredita
Какой-то процент точно переметнулся
на сторону, что не верит в Стальную деву.
