Just as it looked like the site readers accepted Kotoko’s solution, it ends up getting shot down. However, Kotoko had another solution ready. In order to defeat Steel Lady Nanase, she unleashes a second and third solution, but Sakuragawa Rikka and Steel Lady Nanase continue to get in her way. Will they be able to vanquish the ghost?
It's none other than the one who 
was killed, Nanase Karin's father.
.لا أحد غير الشخص الذي قُتل، والد ناناسي كارين
Es war kein anderer, als eben das Opfer
des Mordes, Nanase Karins Vater!
Il n’y a que lui. C’est la victime
elle-même, le père de Karin,
Ebbene, l'origine del sospetto
Só pode ser quem foi morto,
o pai de Karin Nanase.
Не кто иной, как тот, кто и был убит
 якобы ею, — родной отец Нанасэ.
