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?
After being depressed 
and considering suicide,
،بعدما كانت مكتئبة وتفكر في الانتحار
Depressiv und selbstmordgefährdet
fand sie Nanase Karin zufällig
Quizás estuvo deprimida y consideró
el suicidio, y Karin Nanase la detuvo
Quizás estaba deprimida y consideró
el suicidio, Karin Nanase la detuvo
Psychologiquement fragile,
Karin l’avait sauvée du suicide.
Magari, avendo problemi psicologici,
stava meditando il suicidio,
Deprimida e pensando em suicídio,
Karin Nanase a parou por acaso
Возможно, она привязалась к Карин,
когда та вырвала её из мыслей о суициде.
