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?
I just need you to freely make 
your wish in your own mind,
،أريدكم أن تتمنوا بإرادتكم في أذهانكم
Ihr müsst nur in eurem Kopf
zu einer Entscheidung gelangen,
Solo deben expresar su deseo en su mente
Solo debéis pensar en vuestro deseo
Vous devez juste suivre votre cœur,
Basterà che voi lo desideriate nella vostra testa,
Eu só preciso que desejem
livremente em suas mentes,
От вас необходимо лишь одно —
сделать собственный выбор
