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?
So there's no reason to destroy 
my solutions at their roots.
.لذا لا داعي لتدمير حلولي من جذورها
Deshalb braucht sie die Lösungen
nicht grundlegend zu widerlegen.
Así que no necesita destruir
las soluciones completamente.
Así que no necesita destruir
las soluciones del todo.
Elle n’a pas besoin de détruire
mes solutions à la racine.
non ha bisogno di demolire
le mie soluzioni dalle fondamenta.
Então não há motivo para destruir
minhas soluções pela raiz.
Поэтому и мои разгадки
ей не нужно отрицать на корню.
